If, like me, Amazon dropping support for the MOBI for at was news to you then here is an article discussing the announcement: https://blog.the-ebook-reader.com/2022/05/03/amazon-dropping...

This is just a transfer feature, the deprecation is older as I was already unable to source the official CLI converter a few years ago.

The CLI is still shipped with Kindle Previewer 3 software. It's still used internally by Amazon.
