Nextcloud version: 11.0.2
Operating system and version: CentOS release 6.8 (Final)
Apache or nginx version: Apache 2.2
PHP version: 7.1
Is this the first time you’ve seen this error?: Yes
The issue you are facing:
Having multiple address book in my nextcloud account, only the default one “contacts” is synced with my macOS contacts app (resulting in missing contacts on my macOS). Having the same CardDAV configuration on my iOS device, the problem does not occur and all address books are synced there.
Since I haven’t found any indication in the different log files I would like to seek here for help. Thanks in advance.
