I submitted my app to the store, and the review has been approved. However, I cannot find my app when searching in the store.

If your app has been approved but you cannot find it in the store, it may be in the "Waiting to publish" state. This state occurs after the review is complete and your extension is being prepared for publishing. It might take some time before it becomes available in the store for users to find.

You can check the status of your submission in the Partner Center to confirm if it is still in this intermediate state or if it has moved to "In the store," which means it is now available for users.

If it is not listed after a reasonable time, consider reaching out to Microsoft support for further assistance regarding your app's visibility in the store.
