Hello,
Welcome to Microsoft Q&A!
Is it because I made the product unavailable? What is it?
Yes, it is because you made the app unavailable. As the document mentioned here: After you confirm that you want to make the app unavailable, within a few hours it will no longer be visible in the Store, and no new customers will be able to get it.
Please make the app available again if you want to test your app.
Thank you.
