I woke up the iPhone after sending something in iCloud for Notes - and it asked for Apple ID Verification - wanting my Apple PW.
I just said no now and was able to proceed to check notes.
Any idea where that came from - and why?
I did see this - an old post on iOS 9, but same issue and same pop-up appearance:http://www.techbout.com/repeated-apple- ... ups-15372/
At least I'm not alone.
I assume it has to do with iCloud. I circumvented it by going to settings and proceeding on my merry way (all of this was after unlocking the phone of course)
We'll see if it comes back.
