Make sure you are trying to download while you are on WiFi. I would not recommend downloading over cellular data.
Also, if you are downloading over Cellular data, make sure you have “automatically download over cellular data” turned on.
On the page where it asks you to pay again, just press ‘I already have a subscription’. I believe it’s on the bottom left of the screen in blue text. Press that and log in with the exact same email and password you used to buy the subscription and you’re good to go.
