I noticed that in the Gen 8 games when a mon uses Dynamax they have this purple-ish outline while in PS! they don't have that. For example
As you can see the poltergeist in the first picture does not have a purple outline and is like a regular pokemon but bigger while the pokemon in the Gen 8 game has a purple outline. I think the outline makes it look more like a Dynamax mon than when it doesn't have an outline. Sometimes it could be confusing because one mon might be really small so you can't tell the difference between Dyna and non-dyna. Hope this gets fixed.
