[AC Question]

I have a 3rd Gen Moto G, and for the last few months have been having issues with it not saving new contacts or edits to existing contacts.
Sometimes after I save my changes, I'll go back and the changes are gone. if it was a new contact, it's simply gone. If it's an edit to an existing contact, the changes will occasionally revert after a fairly short amount of time.
This happens whether I go to contacts & type in the info manually, or if I am adding a contact from a text or call log.
I have both Outlook & Google accounts running on the phone, but I'm making all the changes through the contact app on the phone.
Any ideas?
