Everyone at this point already knows how much the anime and manga of DBS are different, as you can see in the image above, I've included all of the most important content & ideas exclusives to the manga, and the ones which are exclusive to the anime, at least the ones I could remember at the moment, I didn't count characters with different personalities obviously, or not so relevant scenarios, as Beerus vs Hakaishins, which could have happened in the anime continuity, but it doesn't happening also can't cause any issue.
While some of them aren't something very problematic since they are ideas used only for their respective arcs, others are true issues that literally changes the future of the series, as Transformations.
Any official source pretty much wants us to believe that both are canon.
But I highly doubt that's the case, and that actually, they do know what is the true canon, but they prefer to don't tell us due to marketing reasons, after all, maybe saying the anime isn't canon could make people lose most of the hype on it, we don't know, this is all speculation, and I'm here to do that.
So what exactly are the "3 Canons"? simple, The Movies Continuity (Battle of Gods, Fukkatsu no F, Broly & Super Hero), The Anime Continuity, and the Manga Continuity. Since both anime and movies are adaptations, they can't exactly be the same as the manga, as the Movies can't be the same continuity as the Anime, oh yeah, that's what I'm going to talk about.
Transformations that only exist in the anime, while Goku lost UI after the TOP, Vegeta could transform into SSJB Evolution at any moment, why haven't he used it against Broly? SSJ Blue doesn't seem to waste a lost of energy in the anime as well, he actually mix it with the Kaioken, while in the manga, he needed to master the form (result = SSJB Full Power), also, in the anime, he and Vegeta use SSJB pretty much everytime, while in the manga, only in the critical situations, in Super Broly, Goku used SSJB only when Broly injured him a lot, making him realize that he was a real threat.
There are as well completely different scenarios in both, Characters switching roles in battles, or even using certain powers that doesn't exist in the manga, and in the anime in vice-versa, Goku unlocking the UI.
We can pretty much see how Super Broly is more accurate to the manga, also, let's not forget.
The manga version of them do have a message.
They tell us to watch the movies, now, yeah, you could argue that the reason for this is that both mangas came out before the anime was even released, which makes sense, but, okay, if I can't go by that...
Edit: The message in BoG was actually a note made by Viz, it doesn't exist in the original jp, my bad,
Then now let's talk about the two first movies.
The Movies and the Anime do they have differences, but aside from small details, as Vegeta talking about Tarble in the BoG Movie, I see no one talking about some very important stuff that literally are referenced in the future.
In the anime version of Fukkatsu no 'F', Gotenks shows up in the battlefield, then the fusion ends, Freeza sees it, and do understand by that, they did a fusion. In the movie, that doesn't happen.
Now let's return to Super Broly, where we have a dialogue between Freeza and Gogeta, when Freeza sees Gogeta for the first time, he doesn't know who he is, Gogeta introduces himself as the fusion of Goku & Vegeta, then, Freeza, looking confused, with doubt, says "They've fused?", then Gogeta says "You don't know about that", but wait, shouldn't Freeza recognize that it was a fusion? Gogeta isn't very different from Gotenks. Well, that makes sense, if we consider Super Broly being canon, not to the anime, but to the Manga and the first two movies.
Which makes sense, we all know that Super started with Toriyama having a prepared script, then they gave it to Toei, Toei writers then decided to make all those massive changes to it, while Toriyama's original concepts were kept in the manga. In the movies, Toei doesn't have that freedom, because the movies were directly written by Toriyama due to originally not having manga counterparts. That's why we see them being more accurate to the manga material.
Toei literally created a extra continuity with their version of Super, and that is really confusing, because yeah, I do know, technically, DB and Z also had 3 continuities as well (the Manga, the Movies, and the Anime), but in that case, there wasn't any issue, people always assumed the anime as non-canon, which was obvious due to the large amount of filler material, which is heavily mixed with the canon material, they always made up very clear that the anime was different from the manga, and actually, we all could still watch the anime, that we would understand the actual canon (with just some few exceptions, as Ultra Trunks vs Perfect Cell), and the movies, heh, Do I even need to talk about them? That doesn't happens with Super.
And, seriously, what happened to the anime continuity then? If Super Broly, and probably Super Hero as well, aren't canon to this continuity, then what are they even going to do with it?
In the Anime version of Moro & Granola, will they make Goku use SSJB kaioken? Vegeta use SSJB Evolution?
They can't ignore these forms out of nowhere, this isn't the same case of Cell Arc, where we could understand very well why Goku retired the Kaioken after obtaining the SSJ, without any explanation, it was obvious after all.
Vegeta doesn't acquire any new form in Moro, if he doesn't go SSJB Evolution in the anime, what's going to be the explanation for it? "I'm holding back" doesn't seem to work anymore.
Toei literally ambushed itself, at the current state we really can't know what's going to happen, I love the anime version of Super, but I really wished for a remake more accurate to the manga, I can't refuse that Toei messed it up, but I think that's dreaming way too much. What is the possibility of this happening? Do you also wish that the anime was remade? What do you think they should do when the anime returns? Should the anime continuity and it's exclusive content be completely left out and the "Movie-Manga" continuity be the "only" one? Should the anime be completely different again with Moro & Granola?
Also please don't come with the classic "that's not how canon works, there's no exactly canon" argument, I clearly came here to discuss it and everything is speculation as I said, if there's no exactly canon then that's why so many people talk about it, and that will continue, so please don't get bothered by that, as there are many that still consider what Tori writes as the true story, keep that in mind.
