Vehicle = VW Golf SV with 6.5" Composition Media
Phone = Samsung Galaxy S6
Bluetooth Phonebook v1.2.4 fully paid version
Phone pairs with Radio and all contacts transfer and I can see call history etc.
This however only happens on some occasions - most of the time it pairs, but does not completely sync contacts or call history - in this case the Bluetooth Phonebook app shows "License check Fail" under the PBAP state.
I have already uninstalled the app and also made sure that I have Google Play open when I reinstall the app on the phone.
Please advise what needs to be done to rectify the "License Check Fail" problem.
