After some difficulty I was able to successfully setup Zwift to my Cyclops Magnus via Bluetooth. I ran into a problem downloading the Zwift Mobile App. The Apple App program only provides access to the Zwift application even though you type Zwift Mobile Link. I finally solved the issue by Googling Zwift Mobile Link and downloading that way. Also note that the Zwift Mobile App has a Blue icon whereas the Zwift app has an Orange one. Hope this helps.
