@TeamYouTube I've tried a couple times to sign up for the free trial, but, when it goes to the payment page, it lists a bunch of credit cards I no longer have (expired and no longer in my gPay wallet) with no option add updated info. Kinda failtacular.
Sorry for the trouble! You can add/remove a payment method on this website: https://pay.google.com – make sure you're using an updated Google Chrome browser. Hope this helps!
