So this will affect any book that the firmware thinks is "newly added" on a date after the amazon server was changed.

Assuming amazon refuses to fix their firmware/servers to do the sensible thing, the best possible workaround seems to be for calibre to restore changed thumbnails on subsequent reconnects. This means to send a book to the kindle, with cover, you have to send, disconnect, wait for the Kindle to destroy the cover, then re-connect and have calibre restore the cover.
Hi Kovid,
How can Calibre restore the cover? I mean is there any button or option in calibre? It doesn't happen automatically I believe as I've connected to Calibre few times in the last week.

Kindly share the steps.
Also one small correction. It doesn't remove the covers for all 'new' books.
