Yesterday lunchtime my phone contacts just disappeared from my iPhone 8 - no reason and nothing I had done - all email contacts still there ( over 1250 ) and only a few phone contacts whereas before i had hundreds - tried literally everything including reset from a few days ago from a previous backup - that seemed to solve it with all my contacts coming back and names showing on my iMessages but as the restore continued they disappeared again ? - just can’t seem to get them back ? for them to restore from a previous back up they must have been there but then they disappeared ?
