Can't continue payment for pro checkout

[earnest depot]

Hey, I can't add my google payment on this. It keep saying "You need to sign in to your google account or add a Google payment method to continue" over and over. I did the trial but then i cancel it. And now I want to activate it, but I'm stuck in this loop. I already put the link to my several devices that connected to my google account, but it doesn't work. Please help

I did it to browsers that supports google play, but still popping the same message.
