server ownCloud 8.2.2 (stable)
DavDroid 0.9.1.3 - work good
Reinstall to 1.2.3-ose - grups not work
on the phone most of the groups does not appear at all after the first synchronization.
and if choosing to save contacts to a group, the contact is downloaded to the server without a group
maybe I need to upgrade the server that would all work well?
or you can tell which version davdroid put, where there was no change prevents normal operation?
grups
