Removing Google Calendar and reinstalling.
Removing Google account and re-adding.
Shut down and powered back on
Anyone else having issues where the Google Calendar isn't syncing? In my account settings, the option to sync Google Calendar isn't even listed. I've got App Data, Hangouts, People Details, etc, but nothing about the Calendar. I use the Google Calendar app exclusively, never tried the LG one and hated the Samsung one on my previous phone. I am currently rooted.
