Struggling with Instagram on s21 ultra. Wherever trying to upload pictures it comes up with error messages. Its happened 3 times now. Restarted phone amd and force stop the app. Nothing works.
try clearing cache and data for that app, you'll need to login to Instagram again afterwards though. to clear them, long tap the Instagram icon on your home screen and tap the info icon (letter i in circle). then open storage and use the icons at the bottom of the screen.
