Unable to install ANY apps in texas on child device

I'm in TX and just upgraded my son's Android to an iPhone 17e. I tried using his existing apple account, which I'm not sure what was used for, but it wasn't detecting that Apple Music was licensed to him under our family sharing plan. Every other device I have showed his account includes it. His device, it does not. So I thought maybe I just need a new account. I created one, and still no go. Now he can't install ANYTHING. No apps can be installed. It says content and age restrictions are in place. I go to the parent app, disable content restrictions, they stay on. I find the setting I think is related: Age Restriction. It is hard coded to "Don't Allow" and says below it that I'm in TX and can't change it. I go on his phone, open up the privacy & content, and I can literally as HIM make any change I want, enable x rated websites, no problem. But that one setting is blocked. Two quesitons: 1) How do I get to a point where he can install apps. This device is going back if I don't. 2) Why is he able to change every content restriction under the sun when he's in a family locked account.
