Thanks for your reply.
With each new major version a beta version is available for weeks before which allows users to download and evaluate the new features. This is announced on the Facebook page and group. Any reported issues are resolved and new versions are made available.
With the free version, if you need direct support - it is available, but will require a paid-for support subscription. There are 1000+ daily active users and would be impossible to support everyone for free alongside paying users.
I am happy to investigate issues where there are clear reproducible steps. I tried to reproduce the issue as described and was unable to find the problem.
The Now Playing plugin is independent from the Internet Streaming plugin. Typically with the Now Playing plugin you would configure this to write the currently playing track to disk and then use an external encoder to read this file to send to the stream that way.
