Need help with something on red note tbh.

When I go to change my profile picture for my first time and wait for the loading bar upload my pictures and stuff. i keep staying at the loading bar screen for god no what reason. and idk if it bc i used my apple account for it or something, but i'm not too sure at all so. And yes I added my phone numbers on there already tbh. Anyway, comment below if ya know how to fix that or something. thank you!
