I had my app in the marketplace for around an year and recently found it was unlisted. I think it might be because one of the instances of the app was using the old API. I fixed it but found no way to inform Google so the listing could be activated again.
Today, I found that the listing has completely been deleted from the marketplace.
Can someone help sharing insights on what might have happened or what is the process to bring back the listing? Or perhaps how to reach out to someone at Google to help resolve this?
Many Thanks
The Google Apps Marketplace V1 (GAM v1) is being deprecated, during this process the applications that were not migrated to the new version (GAM v2) were unlisted.
Here you can find information about the GAM v2 and how to publish your app in this new platform. https://developers.google.com/apps-marketplace/
One difference is that the new listing version runs under Chrome web store https://chrome.google.com/webstore/developer/dashboard
