I cannot connect Viber to the hands-free Ford Sync system. Please advise. Thank you.

[AC Question]

I have Viber on my Android smart phone. The Ford Sync system does not find the Viber App.

Is Viber compatible with that? I know for a while (haven't tried it again) Messenger's voice/video calls wouldn't go through BT and always used the phone even if it was connected to a car or BT headset, so maybe that's the case with Viber?
