I had this from alarm clock from 3rd grade all the way until I graduated high school. The night light had stopped functioning and the clock set button on the back was janky AF by the end of it. Lost it at some point during a move or else I’d still have it. Now they go for a pretty penny.
I just went to the App Store and installed that version and it just replaced the test flight version. Nothing was lost and I didn’t need to sign in again or anything
