App Store Payment Method

I need help! I’m trying to download an app (in the App Store). Whenever I try to download an app, I get a pop up saying that I need to verify (ref. figure 1). So, I verify my payment method. Afterwards, I get another pop up that I need to verify again (ref. Figure 2), so once again I verify it. Immediately after, I get the same pop up (figure 2). It’s been repeating this cycle since today. I’ve tried removing my card from my phone and putting it on again but it hasn’t helped. I should mention that I’m trying to re-download Google Maps - an app that doesn’t need to be payed for so why do I need to “verify my payment method” in the first place. I also have NO active subscriptions. Cheers
