I went to the activate screen and entered a code in the format xxxx-xxxx and chose the option to allow. By the time I get back to my Kodi screen (in another room) it is showing a different xxxx-xxxx and I never get past this. Each time I activate the new code it just gives me another one.

This is expected behavior, you must activate twice.
The application name is on the confirmation screen after you input your codes, it is different both times. It will say something like "Choose an account to continue to YouTube on TV" the first time, the bold part being the application name.
Sorry, I didn't make it clear. It doesn't just do it twice. Every time I go back to the Pi it gives me another code. I gave up when it got to 4 or 5 times. What am I missing? All I get is a sign-in on the Pi followed by a code. I go to my PC and enter the code. I go back to the Pi and it gives me another code. This cycle just keeps going. I never see anything about choosing an account. Does the sequence have some sort of time out or something like that? Am I taking too long to enter the code? I entered it within a minute or so. I tried deleting the settings on the Pi and rebooted a couple of times. One time I ran the set-up wizard again. Nothing seems to make a difference.

BTW, it worked fine on my PC version of Kodi and it used to work fine on my Pi. Why did it suddenly want me to activate again? Is this due to the add-on being updated or something? I'm not doing anything different on the Pi to what I did on the PC. Yesterday it wouldn't work on my PC either but today it did. I'm completely lost.
