I know it isn't officially supported, but maybe someone has a fix, or support will do something.     For the official D&D 5e sheet, Roll20 restarts constantly, since around when d&d 2024 was added.     Tested on:  Different iPads.  Every browser I have tried with any settings.   Jumpgate or not is the same.  Other sheets work fine still. It just seems to be the roll20 sheet.  Happens even if you don't open a sheet (and use the app).
