I haven’t had an issue with loading saves until the most recent update. I am unable to load any saves from any world; it gets to loading resources then sits there forever. I deactivated texture packs, same issue. Even created a new world, saved, and I am also unable to load that one either. Ive tried on iOS 14.7.1 and iOS 15.0.1.

I am using an iPad Pro, with 146 gb avail space; def not device related, especially since this just became an issue in the last week or so.
