Also, make sure all connected Apple devices are using the same Apple ID/password account information.
In addition, there is no TV mirroring of the Fitness+ app, using iPad, currently.
Currently there is no direct AirPlay/screen mirroring from an iPad to any other compatible smart TV or smart device using AirPlay2.
Apple, currently has ONLY made the mirroring/AirPlay 2 feature available to owners/users of an actual Apple TV box.
Best of Luck to You!
