Thanks for help, with Synker (and similar apps) it is possible to choose accounts for synchronization AND its possible o trigger it manually!
Feature request : add time of last successful sync
Can you add the time of the last successful sync ?
Because right now we only know of the time of the last sync, successful or not.
It can be usefull if the server is down, and you don’t know who of you or your friends has the last updated calendar.
