Hi,
I updated my Tacx Bushido Smart to new firmware version and Zwift stops see it through bluetooth.
With ant+ everything is ok, but bluetooth doesn’t see the trainer, not mac embedded bluetooth, neither via zwift mobile link.
Maybe your phone has still grabbed a hold of the trainer after you did the update (presumably you did it from your phone)? As a test, try turning bluetooth entirely off on your phone and then see if your mac can see it over bluetooth.
