I love the app. However it is infuriating that shared calendars cannot be added through the mobile app. The fact I have to add the calendar on desktop and then sync via mobile is unacceptable when iphone it's just add calendar and paste the URL within the mobile app. It doesn't make sense to me tha a google product (android) hasn't been able to resolve this issue with google calendar. Sharing calendars shouldnt be this convoluted.
