MCAFEE VPN on t mobile

I have. That is the only way I can get it to reconnect to the internet. I have tried removing the app and reloading it. I have tried loading the specific McAfee for T-Mobile app. Nothing makes it work properly. When the app is loaded you cannot turn it off. It goes to off for a second and then turns itself back on. Cycling it like this will allow the phone to reconnect most of the time.
