Apple TV

I have had Apple TV for years now. I recently ordered a new one which arrived and I set up. I have it set so that it requires a PIN code to buy or rent movies and TV programs. That seems to have all changed, unfortunately.

Yesterday, I tried ordering a movie so I put in the PIN code. Instead of giving me access, I am now required to put in either my long password or confirm on a nearby Apple device registered to me. This is on my Apple TV device. I did use a password the first time but it took a while for me to hunt up the password, type it in and then send it to Apple. The other method is equally cumbersome and it does not work. I tried buying a second movie but used the nearby Apple device method. Sure enough, a message appears on my device asking confirmation. When I click on it, it fails and the Apple TV device tells me it failed. I have tried this many times now and I am frustrated. I do not know why Apple had to ruin a good thing by requiring confirmation but they did and all without advising me, one of many who support Apple, in advance that it was changing its protocols and how to use it. It may seem easy for them but it is, at least for me, a nightmare. I finally had to go to my iPhone, go to iTunes and order the program there. This is no way to run a business. This is very upsetting. If they have to have it, it should say Allow on the iPhone or whatever Apple device I use. There should be no additional numbers, passwords or whatever required. How do I fix this?
