My contacts keep disappearing and when I use the Verizon messages app, they appear as phone numbers instead of the contact name. When I try to view the contact, out appear as a new contact, when I know they are not new. I've tried adding the contract back to my address book on both Verizon cloud and Google. When I log into google on a pc, the contract is still there. In Verizon it's not. This is very frustrating and happens at 2-3 times a week now. Any suggestions?
