I had this EXACT thing happen to me. The time spent on the phone with Verizon, uninstall, reinstall of both apps, then given a website for Apple.

I have an iPhone 12 Pro but this is happening to all phone types, even new iPad purchasers who had a subscription with purpose.
Hello. I was having this same issue and after spending countless hours within the past 2 months chatting with both Verizon and Apple and talking on the phone with them for nearly 2 hours, they could not give me any answers. I was about ready to give up until I decided to do more research. That's when I came across another thread on here concerning this same issue and someone mentioned if your device does not have the latest iOS14, this promo will not work. Since I have an old iphone 6, my software will only update to iOS12. Fortunately I was able to login to my apple account using one of my family member's devices that does have the iOS14 update and when I clicked the promo in the verizon app, the link worked instantly. I then refreshed my account on my phone and was able to finally enjoy this promo. Very thankful for the person who discovered the answer and I hope it helps anyone else who is having this problem. 🙂
