R2 not connecting to VRS could be the result of hitting the "Connect" button in your Bluetooth settings
When you connect an R2 to an Android device, just pair it and then move on to opening your software and connecting there. If you tap Connect in the Bluetooth settings of the Android, it can cause the device to try to connect to the WiFi of the R2 like it's connecting to a hot spot. This can cause trouble when connecting to a VRS because the internet has been taken over by the R2.
So if you're having trouble getting connected to the internet when connected to your R2, go into Bluetooth, click the Settings button by the R2, and make sure that Internet is unchecked.
