I need some help with an issue.

So the issue is that whenever I try and spend money with my phone through starling it declines even though I have like 58 quid and I just wanna buy some sausage rolls for lunch but the issue is that any time I try to follow the purchase up with another attempt I have to "Verify" the card by using my phone password and I do but then go to pay and I have to do it over and over again and it just wont work.

By verify I dont mean autharize, like when you make multiple purchases and have to authorize in the app, I mean my phone UI is asking me to Verify.

Have not tested if cards work, will probably try tonight but I know that I can still send money to payee as I sent my dad 15 quid so I'm not sure whats up and was hoping someone here might now what it could be.

Thanks in advance :)
