I am using Nextcloud contacts for a while, but surprisingly the phone numbers of some of my contacts just disappeared over night. Some other contact cards are removed at all. So far, I can not see a pattern and can not find the root cause for that. Do you might have some suggestions? And is there a simple way to recover all contacts without doing a whole database recovery?
I sync my contacts with Android, iOS and MacOS devices.
Nextcloud version: 25.0.3
Contacts version: 5.1.0
