It seems that the new serviio version 1.5 is not refreshing my media automatic anymore. With the latest version of 1.4 it seems to work fine.
I have added a few new tv series and a few hours later it is not in the serviio database. When I refresh the media with I push of the button it's ok.
I run Windows 2012 R2 server and serviio is running as service with the correct user.
