Marvin's calendar sync is still in beta and you may run into some issues while getting setup and syncing your calendar.

Help! I can't add my google calendar - it fails to authorize

Normally when you setup a google calendar, a popup window will appear asking for permission to access your google account.  If you don't see this popup window, be sure that you aren't using popup/ad blockers or any other privacy browser extensions on app.amazingmarvin.  Firefox, for example, has a built-in popup blocker that you can disable like so:

Help! It keeps telling me to authorize but still it doesn't work after that!

This can happen when you've blocked 3rd party cookies.  Firefox users: see the above screenshot for how to disable blocking for https://app.amazingmarvin.com

Google Chrome users, click the lock next to the website's URL in the top-left corner of the browser window, and click Cookies.

Then select the blocked tab and unblock any cookies you see there.

If you're not sure whether 3rd party cookies on https://app.amazingmarvin.com are blocked in your browser, or if you need help enabling them, please don't hesitate to contact support! 

Help! Some of my events show but not others

Marvin doesn't import transparent google events (those marked busy status "free").
