Firstly, I use Sigil to generate de thumbnail while converting proccess, or you can create the file with correct dimensions.
In Calibre:
Convert the ebook (in my case from epub to azw3)
Transfer it to the Kindle
After disconnect the kindle from pc, the generic thumbnail appears
Connect again the kindle to pc
With file explorer:
Go to Kindle Scribe\Internal Storage\thumbnails\
Sort the content by date. You will see the last file generated after transfering the book and disconnecting the device from pc. The format should be:

thumbnail_....._EBOK_portrait.jpg.tmp.partial

Line ends with ".tmp.partial"
This line corresponds to the last uploaded ebook. It's 0 KB of size.
Select and copy the entire name including the first extension "thumbnail_0b....._portrait.jpg". With the same format that the rest of files.
Rename the thumbnail file created with Sigil or your own method, with the copied text.
Copy the renamed file to this folder and delete the "partial" file.
After disconnecting from pc you will see the correct thumbnail.

I hope this helps whoever wants to see the thumbnails ok
Hi moderators
I don't know if you estimate that this can be uploaded in a dedicated post as a temporary solution to the thumbnail problem in Scribe for the most recent firmwares... although, maybe it's already well known
