MacBook Air running Zwift not pairing with Wahoo KCKR pairing with

Really struggled to link Zwift on MacBook Air M1 to my Wahoo KCKR. Eventually discovered I had to allow individual apps including Zwift to be allowed access to Bluetooth. I entered System Preferences: Security & Privacy: Bluetooth and there was the unchecked box next to the Zwift app, checked it and all was well. Would have saved 2 days of reinstalling if I had found this earlier!!!
