Yesterday, I noticed that some or all metadata associated with important contacts were missing on all MacOS and iOS client devices. For instance, my headshot to my profile was gone and both of my children's contacts were completely lost! When I logged into iCloud dot com, the contacts were missing or incomplete just like on my devices. I called tech support and got no actionable help aside from acknowledging there might be server issues and just wait it out. Poking around the appleid site, I saw for the first time that backups of contacts, calendars, etc. timestamped by date were in there! How long has that been the case? I chose a recent back up and it rewrote all my contacts and everything seems to be back to normal. Has anyone had this issue? How long have the backups been available to us?
