The "Google Home Premium Advanced" add-on to "Google AI Pro" is
$9.99/month. I did verify that once I had cancelled the "youtube premium
add-on" I was able to add the home premium advanced add-on. So it looks
like you can only have one add-on.
The "youtube premium add-on" is an add-on for google one (
https://support.google.com/googleone/answer/15808277 ). It gets me
youtube premium for $11.99 instead of $13.99 it looks like (with AI pro
as part of google one, I'm pretty sure).
What I found out today is you can only have one add-on. If you have the
youtube premium add-on already, you cannot get the home premium advanced
add-on, if there is such an add-on.
