Tacx Neo no longer connects to Zwift on Apple TV

Today, I found that my Tacx Neo will no longer connect to Zwift on Apple TV. The trainer will still connect to Zwift on my iPhone. Also, Bluetooth is working for other devices on Apple TV, such as headphones. Any ideas?

Bluetooth can only connect to one device at a time. Meaning, While Apple TV can receive up to 7 devices your trainer can only connect to one device SO if your trainer connects to your phone then Apple TV will not see it.
Make sure you close all the apps on your phone or other devices that could connect to your trainer.
