I'm using DAVdroid 1.0.2 (but the problem occured with previuos versions as well)
on Android 6.0 with an LG G3, my server is EGroupware 14.3.007
In general everything works fine (syncing Calendar and Contacts)
but changing the time of a calendar entry causes the entry to vanish.
- Set up a calendar entry, e. g. 10:00 p.m.
- synchronize => everything okay, appears also in EGroupeware
- Change time (on phone) to e.g. 10:30 p.m.
- synchronize => entry disappears on phone and also in EGroupware
Would you have a suggestion what is going wrong there?
