as I have the same issue as others I followed the steps described above. I analyzed one specific calendar entry, it is 3 times visible, all parameters (beside Row) are identical except the “_id” parameter. I have uploaded the file …
source are iCalendar feeds from TeamUp (www.teamup.com), if someone wants to reproduce that, it’s a free team calendar.
Syncing calendar feed fails once in a while (I have supressed notifications from icsdroind), so it might be, that these duplicate entries are because of failed syncs?
