There are no issues on the protocol level, the sync succeeds with no errors it's just that not all entries from the phone are in Kronolith afterwards. From the logs I get the following:

To sum up, all events to be synced get into the kronolith_events database but some of them are removed right away during the sync process.

I do not have repeating events with exceptions to be synced so none of the two above apply. But I found the following: A yearly repeating event created with Apple iCal (Test iCal below), synced to the phone and then on to Horde does do ok. But a yearly repeating event created on the phone itself (Test N97 below) and then synced on to Horde deletes all events in the database before being added. I noticed that the UID field gets stripped on the conversion for the server. Could this be the reason? Why does the stripping happen?
