I've been using Pro syncing from Google calendar for a year or so without problems. I am trying to change my Google account, but Rainlendar isn't showing the events from the new calendar. It's very strange: everything shows up in manager, but not in the regular calendar or events view. I enable the old Google calendar, everything shows up fine. With the new calendar, which should be identical, I get nothing.
Update: I'm continuing to play around with this. I am able to pull tasks from the same (new) Google calendar, as well as public holidays, each as separate calendars in Rainlendar. Tasks show up fine, and holidays appear in manager and under events on the desktop, but still nothing on the calendar itself.
