So I don't know what happened, but for some reason, the Activity app on my phone has lost all the information from my Apple Watch over the last 2 years. And right now, nothing is being reflected on the app even if I work out today. On top of that, all the shared information from my friends is missing even though their names are still there. The funny thing is, my Achievements are still there and if I get a new one, it actually shows up. I hope I didn't lose my data, and I don't want to backup my phone because I feel that it would be permanent. Has anything like this happened to anyone else?
