DAVx5 finds all google calendars but doesn't export to Android calendar

[chmeeedalf]

I just installed GrapheneOS, and trying to sync my wife's Google Calendar (shared with my Google account). DAVx5 logs in just fine, and lists the calendars, but they don't show up in the Calendar storage (using Fossify calendar) after switching the Sync switch on. Reading through the verbose logs I see something interesting that may shed light, but this is where my understanding ends:

(Obviously "random_string" and "another_string" are substitutes, as the sync key)

This is using 4.5.8-ose

I'll add that I have a Nextcloud calendar set up as well, and DAVx5 works fine with that calendar. I did test if it's due to my wife's calendar being a shared calendar, but I see the same response with my personal google calendar.

Clearly I am blind. There was yet another calendar list in Fossify that I needed to enable. Everything appears to work fine.
