The app keeps forgetting my phone number and user ID, then locks me out. Or it forgets that my number is registered. Or I'll enter my number and it will say that's not a valid number. Same with my email. When I call support, or go into a store for help, nobody is able to solve all the bugs. Plus if you can't remember your answers the "forgot your answer" link sends you to an error message. This has been happening for months. At one stage the Verizon support opened another account for me. No use.
