It seems I cannot donate in Extra Life. Whenever I choose the "Credit Card" option, it prompts me to input my details properly even when I triple checked that my details I inputted manually is correct and still receive that message. When I choose the "PayPal" option, it prompts me that the payment is not well timed of some sorts. Probably a problem. I can't also choose the "Amazon" option since I do not have any Amazon account and won't accept my (debit) card, and thus my only options are Credit/Debit and PayPal only.
Also I checked my bank account connected to my card and there's still enough amount remaining inside, so it's not a problem about lack of money in my side.
