Was enjoying your app and reading my stories until I tried to pay for my next 3 monthly subscription and it's saying to contact my card/bank issuer as card is invalid. The bank has said it is a problem on your end, as my card is still valid and it's not a Google/Google pay issue as I can still purchase and pay for other things on play store. Your app is the only app that isn't accepting my subscription payments. Please sort it out ASAP as I would like to continue reading the rest of my books
