Adobe's development (and TESTING) folks have been far less than stellar across the board for decades.
And that is why you don't put all your eggs in only one basket.
I have OneDrive and still do backups to my SSD external drives about every month or so.
(I use iCloud only for my iPhone and iPad).
Just chiming in with an apology for this on behalf of our whole team. We take this stuff extremely seriously and there was a major hustle to fix and then a major debrief. This incident was a client side bug in this particular iOS update that impacted a small set of customers using the free version (not syncing w/ our services yet). The team fixed in a follow-up update within 24 hours.
Have you ever used any of the Adobe’s paid software ?
