I was just wondering i have one page with a display form that populates with selected records from galleryA, but i have multiple galleries connected to the same datasource, is there a way to populate this display form from each of these galleries?! Because each gallery is connected to the same datasource, but the display form only lets me populate selected items from one gallery.
I would have to delve more into what exactly you're trying to do before I could help you out. I'm not familiar with that error code. Also, it's been years since I've touched PowerApps and worked within this system... I've even had to create a new account to respond since I lost access to my previous one.
My suggestion would be to create a post with detailed explanation with what you're trying to do (if you haven't already). If you have found the answer, please respond to this post with your solution. Might end up saving someone else the struggle of looking for the answer themselves.
