I am a Web Store extension developer and I developed this speech recognition extension here:
It has a free trial which is working fine. But I need to test if the full version is working. The only way I could think of testing if it can detect the full version is to buy it myself. If there is another way to test this as the developer please let me know.
But when I go to Buy it and select the credit card and click "Buy" I get the message. "An unexpected error has occurred. Please try again later."
But I have been trying now for 20 hours and I still get the same message. I also can't use Google Wallet to make the purchase, it is greyed out so that I can't click on it. What can I do?
