Greetings, i have the same Issue.
Paying with Paypal gives me a Error Message i cant solve/dont know how and whats wrong with it.
It said The billing adress doesn’t match the Adress at my Payment account, however i checked both and everything has the same Adress.
Now i tried to paid with my Visa card an i get the same Infinite payment processes.
In my App it showed me, that the Money already got charged, however after some time, this info vanished.
Tried to Pay again, still getting the same issue.
Cant understand how im supposed to solve this issue and how to Pay on Cubebrush, since they dont let me.
(Support didnt get back to my Messages)
Any Help is appreciated.
