I get about 2 emails a day from users who are trying to buy my app on the Android market but cannot. Mostly due to some credit card authorization issue that they need to fix with checkout.google.com. But this needs to change. User should be notified in the Android Market (We cannot process your order until you update your credit card information), or something like that. But instead they think the order went through (and in some cases it has, but credit card is not authorized, so app never downloads) and they think its a problem that I have control over (which is not the case, except I can cancel their order). Here's a typical email: "Still waiting for it to be downloaded. Tried for about 3 hours yesterday an so far today for about an hour but nothing." Or another: "I purchased your golf app for 99 cents 2 times last night and it is still downloading from 10pm until 7am. I would like some assistance or a refund of my money. I want the app. But its not downloading. Please let me know ifyou can help. Thanks." Android Market/Google Checkout need an alternate process for handling credit card authorization issues.
