I am having a problem with a new Android tablet that my calendar will not load as an option to sync from my Google account. When I go into settings>accounts>sync the calendar does not even show in the sync options. Everything else connected with my Google account like browser/contacts/drive/gmail/photos is available but no calendar. When I go into the calendar app it asks me to set up by signing in with a new or existing Google account, but when I try to sign in with my gmail it says this account already exists on this device and will not allow it...
I have tried deleting and adding the account, and have gone through the Google dashboard but have not found a solution.
Any thoughts appreciated!
