Sorry to hear that the Forget This Device solution didn’t work for you. It must be a more serious issue than I thought. The only thing I can think of is that perhaps your OPNs don’t have the December’16 firmware update yet, hence the connection issue. It’ll be interesting to see if your audi can confirm whether they already are on that firmware update or not.
I wouldn’t be shy at all about walking in to the audi’s office as often as I need to. It’s them that should be ashamed that they have taken that long and that many visits to get you set up properly with the OPN.
