This app worked brilliantly with my previous car. Now I switched cars (Audi A3 with MMI plus). Syncing messages seems only to work when te app is really active. The app shows then: connected to Audixxxxxx, but as soon if I let the phone be idle, It looks the app looses connection with the bluetooth. (Phonebook app says: Last connected with Audixxx and some date.). I'm starting to think the PBAP profile gets switched again few minutes after my phone is locked again.
My issue looks terribly similar to this one:
thanks in advance
