So the same as other people with the new update for users on Android it freezes and lags. The workaround I found was you have to go into your settings and go to apps and clear the data in the GrubHub driver app and it makes it not freeze anymore but it's a hassle to have to do this every time. Tonight I logged in and the app was back to the original way so I don't know if they're listening and changed it or not
