According to Android Authority (
https://www.androidauthority.com/202...ading-3494778/), Amazon has stated officially that D&T won't work on any of the 2024 devices. The quotation appears below. I could not find the source of the quote directly.
Viz:
Customers can connect their new Kindle devices to a computer to transfer files. On Windows, it’ll appear as Kindle in File Explorer. On Mac, customers with the new 2024 devices will need to install additional software (e.g., Android File Transfer or OpenMTP). Customers can still transfer books and documents from their computer via USB or use the Send-to-Kindle service. They can no longer use My Content & Devices to download and transfer books to the new 2024 devices via USB. Content available in My Content & Devices is visible on the device in their Kindle library.
