Weird request, but I'm interested in watching Adventure Time in Castilian Spanish, and I don't mind paying to stream it. I live in the US with a Max subscription, but Adventure Time is only available in English on it. HBO Max still exists in Europe, and apparently the Spanish translation is available there. I've got NordVPN and am connected to a Spanish server. I can install the HBO Max app and create an account, but when it comes to pay for the subscription it won't take any of my credit cards and Google Pay says everything is unavailable to use "in my country." I've tried buying a prepaid card with 10€ from dundle.com, but nothing will go through.
How do you go about making payments to geoblocked services?
