iPad Photos thumbnails corrupted
My thumbnails have gone completely haywire, with them looking nothing like the picture behind them. The thumbnails were from pictures in my dataset, but completely wrong. Whenever I clicked on them, and in some cases zoomed in by tapping, they them went to the correct picture, but the wrong thumbnail persisted when I then went back to the Library view.
I only sync using cable, I don't use iCloud for photos and my source photos are all on an iMac, stored under the Apple Photos for Mac app. I have iPadOS 15.3, iPad Pro 3rd Gen.
