Okay, so I got it to work on an iPad the other day. You have to set up as usual on one of the fully featured apps like android or Windows and then log in on ios and select external player (vlc). You can also save the page as an app to your home screen.
No luck on tvOs as far as I know though.
This was also my initial take but look at these graphs with the Y axis starting from 0 Stock lost 67% value in the last year alone, and lost 85% in the past 5 years. Looks pretty dire to me. I would say this is undervalued but I have no confidence in the ubi leadership to turn it around.
