Diagnose
Checkout >>> error message
Prerequisites: Blocked checkout.
Step 1. Read error
Payment failed on form.
Unable to start checkout / Invalid plan or pricing for bad URL params.
Step 2. If charged without access

Key points to consider
Amazon Pay / wallet redirects historically caused fulfillment misses — use card in production.

Using unsupported currency param — only six ISO currencies.
Read checkout error, fix params/card, contact support if charged without fulfillment.
