PayPay credit card help

So I decided to get a paypay credit card as a back up for emergencies.

I bought a cup of coffee and a sandwich with it last month to check it works and it's all fine.

However I like to pay off in full every month and I can't it for the life on app see an option to pay in full and clear the card.

There is only an option or revolving payment or splitting. I have tried the revolving payment but all that did is defer repayment date further down the month.

Annoyingly I can't log in to banking on a web browser as it's telling me to log into Yahoo and apparently my Mobile number has been blocked for violation (unsure why and they won't tell me).

Is there an easy way to resolve this?
