EDS' "Data source does not support OAuth 2.0 authentication" error sometimes prevents seeing any Google Apps for Enterprise calendars
I'm unable to access any of my Google calendars in gnome-calendar-46~beta-2.fc40. It's as if the calendars are just not there: GNOME Calendar does not display any warning or error message of any sort in the UI (#17). The Google account is configured using gnome-online-accounts.
(gnome-calendar:39093): GcalManager-WARNING **: 10:19:39.553: source_credentials_required_cb: Failed to authenticate 'mcatanza@redhat.com': Data source “mcatanza@redhat.com” does not support OAuth 2.0 authentication
That's strange because this is Google, which surely does support OAuth 2.0.
