Calendar integration on Android

I have tried to add my Google calendar to the new android beta app but it doesn't seem to work. No errors, logged into account fine and granted permissions, returns to app home screen but no integration added.

Another option would be to support local calendar accounts (seen other calendar apps do this and pick up google account calendars)
