Apparently the same as No sync settings for calendar & contacts, please follow up there.
Some contacts are not synced from Owncloud
Most of my contacts are synced from Owncloud but few are not. I can’t find any relation between the contacts which are not synced. The issue should not be related to Owncloud has I used another cardav app before without issue.
Is it possible to collect some logs in order to identify the issue?
Owncloud version: 8.1.0
Davdroid version: 0.8.1 (from fdroid)
Phone: Cyanogen 11 M11
I guess that this is a duplicate #578, as @untitaker said. Please follow up there.
