I was having this intermittent problem with Carplay being paused during an incoming call instead of picking the call up. I could not hear the caller and had to reboot Carplay to get out of the "paused" screen. I got to thinking that pairing my phone with the MB system AND using Carplay was causing conflicts when the phone rang. I unpaired the MB system from my phone and the problem has vanished. Hope this helps anyone having the same problem.
