0013230: CalDAV Sync on Android generates duplicate events #6546
Reported by shochdoerfer on 17 Jun 2017 10:36
Version: 2017.02.3 Community Edition
For a long time I am using CalDAV-Sync to sync Tine 2.0 events to my Android phone. Since a few weeks reoccuring events get duplicated on Android during the sync. Like one appointment appears multiple times for one day on Android. There is one appointment that got duplicated like 12 times.
I recently upgraded to latest Android 6 version for my phone (PLK-L01C432B390). Are you aware of any similar issues?

Similar issues are only known to me when using the SyncToken feature in Tine20. Never worked for me, hence this can be switched off in config.inc.php.
Only other thing I'd try is to delete the caldav collection completely and set it up new and see what happens.

I trust you deleted and recreated the caldav account on your phone after you disabled the SyncToken support?

I deleted and created the caldav accounts multiple times on my Android device, even after disabling SyncToken support. Have not had a look at the looks, need to figure out how to filter them best ;)
Wired enough the sync works fine for me in Thunderbird/Lightning but also screws up for one of my co-workers with Thunderbird/Lightning.

The issue still exists with the latest version of Tine 2.0 and regardless of the Android client. Got the same problems with the software CalDAV-Sync as well was with DAVdroid. In DAVdroid I can see that all my calendars are available multiple times, not sure why this is happening. This might be the root of the problem.
