Can't add link to WebGL project

Mission: Explore Unity
Tutorial: Publish your project

Unity Learn won't accept the link to my published WebGL project.
I had to publish it somewhere else other than Unity Play because due to a bug I'm currently not able to access Unity Play.

Alright mate here ya go.

So I was on another part of another lesson, namely Junior Programmer on the "Mod the Cube" and it asks for the same thing, upload a WebGL link. Now it is widely known that WebGL won't work on conventional browsers (Edge, Explorer, Google), and while it was rumoured it worked on firefox it doesn't, or at least at the moment it does not. What works in firefox that doesn't work on other browsers though is Unity Play, which you can then post your game and send the link. I am not sure if it will work by the time someone else sees this but, it takes like 2 minutes to download firefox and if it works you are certainly saving yourself a lot of time.
