Are iCloud notes saved if the phone is deleted/restored?
This is probably a basic question, but I previously was only doing all my (extensive) note-taking using the "on my iPhone" option, because I believed that if they were in the cloud I wouldn't be able to access them when I'm offline. I recently had to restore my phone, for the first time ever so it's hopefully very rare, but now this total-deletion issue is on my mind. At the time, my iTunes backup was 2 weeks old, so I lost some messages and notes, so I decided to switch to iCloud notes.
Here's the basic part: if my phone crashes again, are those iCloud notes saved? (since they would no longer be part of an iTunes backup?). I feel like...they MUST be, since the syncing means I can see the same notes on my desktop app, through a web browser, and on my iPad, so they shouldn't just disappear if my iPhone is deleted. However, because iMessage did not "re-sync" back to my restored phone (I believe this is because I'm not using 2FA, though?), I'm wondering if iCloud notes could possibly be lost during a restore. (if so, I'd change certain notes back to "on my phone").
