I think I figured it out. i Have two homepods, one with AppleCare+ and one without. When I go to install the profile it only will give me the option for the one that has AppleCare. if You look when installing the profile it says the profile is signed by AppleCare. I’m going to take a guess that the profile is only installable on homepods that have AppleCare+ because the software cannot be rolled back if something happens.
