Setting up payments for some activities not possible with a "prepaid card" e.g. Google Ads.
Agreed - couldn't use the card with Google Cloud Platform but fortunately could set up a direct debit.
That is why I have stopped using counting up for the moment,
Some people are uneasy making bank transfer with a sort code that comes up with PREPAY TECHNOLOGY LTD
Same for Uber and MyTaxi apps .... and i get a LOT of taxis
