If the calendars appears in the settings and in the manage calendar page in the calendar application (and their events also appear in the application), I think it may come from the fact that calendars are seen as read-only, or seen as not suited for events (allowing only todos or journals).
I don’t see super much logs, but it does say ‘loaded notebook “” from database’ for all the calenders, the default, as well as the 5 caldav ones and the b-day ones.
the caldav calenders are also allowed to have TODO, but should that make it readonly? should i try to add a calendar that does not have TODO?
to be sure: the one called Personal (Default?) is the only one that is suggested, the b-day one is also not in that list for making a new appointment.
I wonder if any unknown property in the calendar makes it readonly? would anyone have a suggestion of what props should work with a caldav to make it writable? does anyone have a props example from a working writable caldav calender?
So, i tried adding a calendar without todo, then i added a 2nd caldav account (with a copy (actually symlink) of the calendars) and suddenly all calendars (with duplicates) were suggested for a new appointment and I could edit existing ones back & forth…??? I have removed the 2nd account and it still works. did something happen during the first adding of the account? did i have to add a 2nd caldav to make it work? i don’t know, but i guess it works now?
