PhoneBurner has the ability to sync Appointments to your Google Calendar. The instructions below can help you sync for the first time, remove an existing Google Calendar, or change the Google Calendar that is synced.
First, go to your circle icon in the upper right of your account and go to My Account from the account icon upper right, then to go Calendar>and Sync with Google Calendar and choose the calendar you want to connect to at the bottom.
Note: PhoneBurner only supports syncing with one Google Calendar.
There are some instances you may need to remove the Google Calendar integration or switch to a different email address (such as your work email, instead of personal email).
Go to this link: https://myaccount.google.com/permissions
Sign in to the old account, the one you wish to disconnect or remove from your PhoneBurner Calendar.
Click on the Google Calendar Integration section, and then select Remove Access (Pictured Below) and then go back to your PhoneBurner account and follow directions above to choose your new calendar to sync too.
Click "OK" or "Done" on the pop up window.
If you would like to switch your PhoneBurner calendar to a different account, sign out of Google, then return to your PhoneBurner's calendar settings. From here, you should be able to start the new connection and sign in to the newer email, the one that you would like to sync going forward.
