[Kindle] Problems with cover and title.

[mrboh]

Hi,

I'm sorry if I write the same thread already written in another section, but I don't know how to delete the previous one, in the Amazon Kindle section, and I think this section is more suitable for my problem.

I'm having trouble viewing my ebooks, treated with Calibre, and sent to my Kindle Paperwhite 2019.
In the beginning I passed all my books in .mobi or .azw3 format and they were displayed perfectly, with the title in the format I chose and with the cover. Then suddenly, after doing a synchronization of my Kindle, but I don't know how influential this operation can be with the problems that arose.

The first problem was not to display the covers on Kindle home, both for the .mobi and for the .azw3 format.
I solved this problem, but only for .mobi files by selecting the "Enable sharing of book via facebook ..." item in the "preferences -> output options -> mobi output" section, activating the same option in "azw3 output" for however the .azw3 format does not change anything.

The second problem instead concerns the title of the books displayed on the Kindle, before everything worked well, now no longer.
For the .azw3 format everything ok, I set in preferences in "metadata plugboards"
azw3: KINDLE2 = ([{pubdate} • {series: ||:} {title}] -> title})
While for the .mobi format I see only the title of the book even if in "metadata plugboards" I have set
mobi: KINDLE2 = ([{pubdate} • {series: ||:} {title}] -> title})

By unchecking the "Enable sharing of book via facebook ..." item in the "preferences -> output options -> mobi output" section in the .mobi format I do not see the covers nor the title of the book in the format I would like.

Thank you so much for future answers.

and you are probably generting joint MOBI files for which updating of metadata is not possible so plugboards wont work.

Please do not post the same question to multiple forums on MobileRead.

Hi,

I read the linked discussion, I tried, as suggested in the discussion, to load one book at a time, then save the cover by replacing it in the hidden folder of the Kindle "system / thumbnails", a bit complicated as a thing because it would force me to load a only book at a time and each time disconnect the Kindle from the PC and reconnect it, but I have seen that the thumbnail created is actually that of the loaded book, but the one displayed on the device is the default one of the Kindle.

Can I generate "not joint" mobi files?

Thanks!

UPDATE: For the azw3 files ven in airplane mode the behavior is always the same, Kindle with default covers, and covers in the thumbnails folder.
But for the mobi files, if I choos "old" in mobi output options, everything seems to be going well.
