I am faced with the problem that events created with aCalendar+ are synchronized with status “TENTATIVE” and hence shown as “tentative” by the Lightning plug-in of Thunderbird.
The aCalendar+ developer told me, that he does not set the “tentative” status and that the problem must be related to the sync adapter.
My configuration is:
DAVdroid/0.5.14-alpha from Google Play Store
Sony Z1 Compact running Andoid 4.4.2
OwnCloud 5 hosted on WHS 2007
The debug log is available at:
