Hi, JenniferV !!!
How are you doing ?!?
As I said, used to cast UTube content (UTube video's audio track only) to my ChromeCast Audio via TUBECAST --- a third-part developed app that's rendered faulty and currently unsupported by the developer.
Do you know of any similar or substitute app ?!?
Best regards from Brazil !!!
