I have submitted this bug since beta 4 and I have gotten no response, nor any signal that others are having this problem.
I can't put any apps in folders. No matter how I try, apps "fall" right through the folder.
Even if I have moved the app around in the folder, it'll fall right through the the homescreen.
This only happens on iPadOS. I have restarted obviously. I really don't want to do a full restore, but at this point, this is what I am thinking I have to do.
I am using an iPad Pro 11 inch. Latest iPadOS beta.
