Launch your current browser and open a Private or Incognito window.
Navigate to Microsoft AppSource, log in to your account, and attempt the purchase again.
If it still fails, try using a completely different browser such as Microsoft Edge, Google Chrome, or Mozilla Firefox.

Frequently Asked Questions
Why is the AppSource Place Order button grayed out?
This usually happens when the web page's validation script fails to register that all mandatory fields are filled out. It can be caused by unsupported payment details, incomplete fields, or browser extensions blocking the script.
Can ad-blockers affect Microsoft AppSource checkout?
Yes, aggressive ad-blockers or privacy extensions can sometimes block essential background scripts required to validate your payment method and enable the order button.
Does clearing the browser cache actually fix checkout issues?
Yes. Corrupted or outdated cache files can prevent newer versions of a web page from loading correctly. Clearing your cache forces the browser to download the most recent, functional version of the checkout page.
