I have a Moto G 3 phone. I have been using the calendar since I got it. Suddenly. all my entered data is gone and I can no longer add new data. Is there a way to recover my calendar data and use the calendar again?
Check to see if your calendar information is here:
If is, then it hasn’t disappeared but instead just isn’t syncing with your phone. Let us know what you find.
You can also find the sync settings in the Settings app of the phone and under your account settings somewhere in the middle of the list.
