In Memotoo I have two events with yearly interval, but at the first thuesday of the month instead of a fixed day. In Evolution these events are non repeatable events after sync. I downloaded my data from Memotoo, opened the calendar file and searched the event. The rule are:
If I change this in Evolution, after sync the repeats are lost at Memotoo.
The same is with frequency monthly and interval 12. It seems there is some misunderstanding between Memotoo, Syncevolution and Evolution. And in Evolution I can only choose monthly if I have not a fixed day.
Looks like a conversion problem of the recurrence rule. I can try to replicate this, but don't hold your breath.
It turned out that the Synthesis engine lacks support for RRULEs with BYDAY/BYMONTH values including a number (e.g. "first Monday"). It only supports BYDAY=MO, not BYDAY=1MO.
I'll keep this open as a feature request but don't have time to work on it myself at the moment - sorry.
Thank you, Patrick. Because of such things I changed from SyncML to CalDAV a few months ago on my own server. There are no such problems there.
