I've had Apple Music on 3 devices plans for 5 months now (play more unlimited), one of the 3 phones will not activate Apple Music. All 3 devices have their own Apple ID, and none have an ESIM. I spent hours on the phone with Verizon, even had them linked into my phone to see what happens remotely and they couldn't fix it. They sent me to Apple, who, after multiple hours on the phone concluded that the issue is with Verizon. Apple can see that I have a plan but they can not control the activation through Verizon apparently. Verizon has had me cancel and reinstate Apple Music multiple times now, and every time I get to the part where you click the link to activate the account I am taken to a page where I can sign up to pay. I activated the other two accounts without issue, I don't understand what is happening here, it's so frustrating!!
