need help with WebGL publish stall / fail

Hi

Published a WebGL project from the Unity editor; no problems there.

Clicked “Play” and got message “The first play through is recorded to add a preview of the game.”. But nothing else happens after that. Blue progress indicator sits at 0%.

What am I doing wrong, or what do I need to do to solve this?

Thanks in advance.

EDIT: this is happening in Chrome browser. It works in Safari.

This has been resolved. Posting here in case it helps someone else, later.

  • Rebuilt the project using a newer version of Unity (2020.1.16f)
  • I forgot to include a scene in the build settings. Simple mistake, but something I know better to not do.

Hope this helps.
