Apple TV not working on second Apple TV 4 device in seperate room, it works in Bedroom but the Apple TV in the living room does not work I have the Apple TV 4 on each tv.

Yes I have two Apple TV devices one for each tv. Can I get by with just one for both tv’s ?

if I can please let me know how to set it up if I can’t then I am able to watch the tv in living room using my iPhone 11 as a remote I only have one Apple TV remote and I’ve asked Apple many times how do I acquire a second remote to replace the one I lost and the answer was I would have to buy appletv device to get its remote as they do not sell just the remote.

I will know more once I find an Apple store opened for business so far the one in a mall I’ve used in the past is not open any longer as far as I can tell. I’ll return with more information at a later date thank you for your responses
