Issues caused by restoring from backups were super common in the early iOS days. It makes me wonder how many weird bugs can be fixed these days by starting from scratch instead of migrating years of cruft through backup/restore.
Quite a lot probably. I wasn’t able to use the health app on two different iPhones - it would crash after tapping “get started” consistently - and apple told me to just start from scratch instead of restoring from backup and there was no other way to fix it. Not a very satisfying answer
