I don’t know how to fix your problem but I am curious about it.
I assume you have an old iPhone tied to your iCloud account. What happens if you untie that phone and wait like a day (some iCloud stuff is weird and can take about 24 hours to update server side info)
Are you the OP in that post?
This screen comes up when you add an Apple ID. I recently signed out of my Apple TV and got the same screen. I used the physical remote and entered my credentials. I didn’t need to use my phone, even though that was an option. Maybe this was an issue with iOS 16 as the post is a year old.
In order to update my Apple TV, they tell me I have to have a newer phone.

Now you can use it, but guess what is required for future app updates? Later OS updates. It’s a trap.

You can enter the credentials manually. I just did it few weeks ago.
