Mine doesn't load either. I've uninstalled and reinstalled the app and plugin and it's not helped.
Did you end up working it out, I just got the game and am bummed I can't play, I got this exact issue.
No. Going to side load it onto my Chromebook instead.
i got it to work, so turns out the joiplay version on their website isn't the newest version? Wtf... Try downloading Joiplay from their patreon, after I done that it worked no issues.
