Profiles gone from Apple Fitness TV

Hope someone can help. Mine and my husband’s profiles have disappeared from fitness on the TV. I have the Apple TV box which is fairly new. I can get it on the TV by starting the workout and clicking AirPlay but I never used to have to do this. Once I connect on my bk phone or watch, it was automatically on the TV. It now prompts to set up using one of the devices but there is nothing there to do that when I open the fitness app. Help please!!
