I looked at Adobe's list of supported ebook devices/apps for use with Digital Editions and found that Mantano Reader--currently installed on my Galaxy Note 4--was on the list. I then followed the directions to connect the tablet to the computer on which the eBook is located with a USB cord. (The computer sees the tablet.) Then I opened Digital Editions per instructions, but the device doesn't show on the left side (or anywhere else) of the window. Therefore, I see no way to transfer my eBook to my tablet. Any ideas? I tried using Samsung Kies--the file isn't in a format that Kies sees.
