Hello,
I have following setup in place: Calengoo on Android - (local android calendar) - DAVx5 - Baikal CalDAV
New appointments created in Calengoo are duplicated in a special case:
- connect with DAVx5 to CalDAV server and name the account abc@xyz.com
- add an appointment in Calengoo and invite abc@xyz.com to the appointment
- force sync in DAVx5 for the calendar of the account “abc@xyz.com”
- appointment is duplicated
You can change the name of the account in DAVx5 to something different: duplicates are gone
Rename it back to abc@xyz.com and create new appointment with abc@xyz.com invited: duplicates are created
Duplicates are not created for existing appointments, only new
Creating an appointment in stock (LineageOS 16) calendar will lead to same behavior
Regards
