iOS app opening a note PiP every time it opens

[BrettWysteria (Brett)]

I can’t possibly be the only one this is happening to. So this little Picture in Picture window keeps popping up every single dang time I open the app or even switch back to it after using another app. Why is this even a thing and how can I prevent it from happening again? Apologies if this has already been posted about but I don’t even know the rights words to use to search for something like that. And if it’s been asked before it should be pinned or just fixed by the devs.
