Amazon shows my book is “Temporarily Out of Stock” for over a month now

I published my paperback version on KDP. A few days later, I made a tweak, republished the paperback (I now know this was not ideal), and also published the hard cover with the same updates (this was the first time publishing the hardcover).

The hardcover published fine after a few days and is in stock. The paperback still shows “Temporarily Out of Stock”. It has been over a month now, so I don’t believe it is still in the “calibrating and syncing” phase.

I’ve called Amazon twice and both agents mentioned it is a known issue affecting many authors, they don’t have an ETA on a fix, and there is nothing I can do except wait (possibly months?). I figured there’d be a lot more details from others if it was that wide spread.

Has anyone else encountered this and been able to fix? Or anyone else in the same boat?
