I have been using the MetaTrader 4 app on my android for over a month, worked great for what I was using it for. One morning, I logged in around 7:00 am, worked fine. Tried logging in later that morning around 10:00 am and I got the error, Authorization Failed. I contacted the broker to see if something happened with my ID and PWD. It hadn't, ID still works on my computer version of MT4. The broker is seeing no failed attempts on their server, meaning it must be originating at the phone. Verizon said they don't have anything to do with individual apps and can't block access like that. Anyone have any ideas? I have uninstalled the app and reinstalled it, didn't help.
