Anyway, Dropbox PocketBook and PocketBook Cloud can be used at the same time. Each has a different function. With Dropbox PocketBook you can bulk send books to the e-reader. With PocketBook Cloud you can choose whether or not to sync them to other devices (or simply store them here so that they do not take up space on the device).

For example, I only read PDFs on the InkPadX and don't need to have them on other devices, so I use Dropbox PocketBook to send those books, but I don't upload them to PocketBook Cloud (although you can have them stored here too and not download them to other devices) . Or you can have only one device to read and you don't need to sync anything. In this case you can use only Dropbox PocketBook or only PocketBook Cloud at your choice.

I would like to have in other brands the problem of which option to choose: PocketBook Cloud, Dropbox PocketBook or Send to PocketBook (or use them all at once) . It seems to me that this is precisely one of the strengths of PocketBook. I don't understand how it can become a problem.
