Hi all, so you know. If you have paired any device to the wahoo fitness app, they are rarely able to connect to zwift. it takes seconds to pair devices to the wahoo fitness app so just add and remove each time you use it. it has something to do with the device check rate. zwift checks the devices only after the app is running, the wahoo app runs in the back ground. they don;t like share the signals.
If your using zwift and wahoo devices, your best bet and it has worked for computers, apple tv and ios devices. is to NOT use the wahoo fitness app when using zwift.
For IOS devices, removed paired devices from wahoo fitness app only, clear all background apps, do a hard restart (Lock and home buttons together , quickest) open zwift. you will be good to go. It sounds like a pain, but start there and work your way up by removing a step and see how you go. any issues revert back to this to clear any problems. The computer is the same your phone needs to have Bluetooth blocked for it to work, and you do not pair it to the computer just detect from the zwift program. windows gets confused.
