I am a newcomer to elementary OS.
I am struggling with syncing Apple Calendar (iCal) in the elementary OS Calendar app. I tried to "make it public; copy URL and login with iCloud Login/pass" - but it keeps asking for iCloud credentials and doesn't sync.
The same issue happens with Google Calendar, with a personal Gmail account and with a Google Apps Enterprise account, both with 2FA enabled.
In the iCal issue, I really don't know what to do. Google Calendar wise, I didn't try to setup using "App Password" option, yet. Thoughts?
I am using the latest eOS Loki's update.
