What's Wrong?

When I created a game in run.game I am trying to share the game link with people but I keep getting this error msg on a white screen writhing the run.game app. And the design code states I can’t have a in browser link people have to have the app to play.

What Should Happen?

Either I need a browser link that anyone can use on any device or a way to access within the app.

Steps to Reproduce

Publish game on run.desgin and publish it, once published send private link . If private link works I’m unaware why I can’t do this. Maybe because i have an online creation game mode?
