### 1/5 — Unable to pay for the app.

*2025-09-15*

I tried to pay for this app, but it doesn't work. It says the payment failed. My credit card is in perfect condition. I can successfully buy anything else from the App Store with zero problems. I don't know why they make it so hard to give them money.
