I'm rocking and rolling in Solus right now. I did not get the javascript popup error though.
I'm in Budgie and fully updated.
And rocking.
Uninstall it and install it again, see what happens.
Does it play music or not?
**It's weird the appimage doesn't work either.
ps--I was just saying to myself yesterday that 'I wish I knew how to work Flatpak from --help
menu.' you can debug from there but I've never tried it.
