There is also apparently a Wahoo firmware bug that some people are running into, workaround is making any change to the wheel size setting in the Wahoo app. This is easy and harmless so might be worth trying.
However that would not affect pairing the Play controllers to the Mac, so that may have another cause.
You could also try doing a clean reinstallation: Re-Installing Zwift
I think if the problem were a game release bug we would be seeing a lot more reports like yours, since your equipment is widely used. If you contact support they can also look into your game logs to see if they can spot a problem there.
