Thanks @sarsan for notifying us.
The problem has been fixed (in the coming version).
OK
folowing your recomendation, exteplayer set on, "refresh green button" not see it. see pic 1
please see pic.2 - option "playlist" if picking channels from THAT list there are missing
The green button currently appears only for portal channels and will be revised for other types.
wish new version will come with "green restart button"
