I have an iPad 10.5 and an iPad Mini that can only be updated to iOS 12.5.7. The problem is the version of Disney+ that is installed needs to be updated. When I hit update it takes me to the app store. I choose update again and get a prompt asking if I want to download an older version of the app. I choose download and nothing happens. The prompt just comes back and no matter how many times I hit download the prompt just keeps coming back. Is there a way I can use the app without getting a new iPad?
