Many thanks not expecting a reply so soon but that's great
it is an Android TV boxH96 pro not sure if it's I'm in the right group
I was going to install another file browser but it won't let me run anything including MP3
as you can see it shows a tick mark and does nothing else I was thinking it's associated with the wrong App something like that
the mp3 looked like it was associated with Gallery in the file browser I went to Gallery and I could run it from there
I am thinking about resetting the unit and starting again but not sure where to get all the apps again like Stremio etc.
also, it would get rid of the constant pop-ups adverts.
Thanks
