An error was found in version 4.0.0 and 4.0.1 of the DME client for Android: Folder synchronization did not work when synchronizing against a version 3.5 server.
Folder sync. now works correctly with all supported servers.
Version 4.0.2 will be released on Google Play and on this site on Tuesday morning, July 31st.
In about one week from now, the DME client 4.0.1 will be released on the Apple App Store.
The main reason for this release is to fix an issue where the client could crash when an e-mail was deleted (on iPads only).
Apart from this, a new feature has been added: You can now use DME to e-mail attachments from 3rd party apps instead of having to use the built-in (usually personal) mail account - if attachment uploads are allowed by the DME server settings.
