Actually, the rsap app works fine with my Mi4i, but only one time.
As soon I disconnect the phone from my Premium FSE in my Skoda, the phone won't find a network again. The app says "ending SIM access" (SIM Zugriff beenden), but the ending doesn't end.
I always have to terminate the rsap app, switch the phone to flight mode and back on. After that, the phone works fine again as well as the rsap app.
Is there a workaround?
Btw, it got better after the 3.0 release. Before that I had to reboot my phone everytime it was connected.
