I am using Seafile Server 6.0.7 on Ubuntu. I have some android clients connected to this server.
In the admin panel, the version number of the android apps still 2.1.5, although all of them are using 2.1.9.
The only way to get the correct version into the admin panel is to reconnect the app.
It would be nice if you could have a look on this issue, but it is not very dramatic.
