I have a question which is also a slight problem. I am using gnome-online-accounts within Gnome-Shell. So it is synchronising contacts, calendar-events and email.
So here the question beginns: in case I can not get online, I do not have any calendar-events. The gnome-calendar is empty and so is the drop-down menue on top of the screen.
Is there a way to keep those events in a local cache?
Thank you so much for your help.
Sebastian (using gnome-shell 3.18 and newest updates from Antergos)
