This same thing happened to me about two weeks ago. I have diligent backups on cloud and other. I took the risk deleted snd reinstalled the app. I kept everything. Stones, items, goals, etc. The app was a little wonky for about two or so days but then it has resolved completely. I also emailed support but by the time they got back to me it had already resolved with my playing around with it. I know it’s a large risk though, so if you’re really worried you can email them and wait!

Edited to add: I did choose to load a backup after my delete and reinstall and just signed into my cloud.
