My configuration is as follows: Boxcryptor Free and OneDrive cloud storage on laptop computer (Windows 10 Home version 1809) and mobile phone (Android 6.0.1). From the Boxcryptor folder on the laptop, I can easily get the unencrypted version of a file to, for instance among many, attach to an email. On the phone however, in the same operation, it is the encrypted version that gets attached. And when I try to download a file locally on the phone, nothing happens: no file downloaded, no error message, nothing. All I seem able to do on my phone is to see on the screen the content of files I have under Boxcryptor.
