Q: touchpress app on appletv4 not streaming content?

Greetings,

As a lover of Classical music the touchpress app was one of the first apps I downloaded for Apple TV.  It worked fine until a few days before Christmas.  About that time it seems unable to stream content anymore.  When attempting to play a piece of music the preparatory and loading prompts show up properly but once the "windows" are in place and the music should begin to stream the apps just stops as if it isn't receiving the content. 

I have deleted and reinstalled the app several times.  This did not fix the issue.  All other apps (YouTube, PBS etc) stream fine so it doesn't seem to be an internet connection issue.  I have emailed touchpress support - so far no reply.

I don't believe there is a way to post and see reviews for Apple TV apps - if so,  I would have directed this inquiry there.

Is anyone else with this app having the same issue.  Perhaps it is something unique to my setup but as I said, other apps perform fine.

Thanks and regards,

David
