I'm experiencing a bug in beta 2 that neither my iMessage nor FaceTime recognizes my phone number - only email. I've tried logging out and back on, restarting my iPhone 6s plus... Any tips?
Log out of all services and then reboot. Log back in after you reboot.
If that doesn't work there is another similar troubleshooting method.
Log out of all services, reset network settings (you will lose all wifi passwords), reboot, sign back into your wifi and then log back into everything.
