Choose Your Environment Screen is Missing

First time using Flywheel and I’m trying it out based on this Using Local by Flywheel with other CMSs — Tyssen Design and another article https://medium.com/@madebyraygun/a-quick-and-easy-local-environment-for-craft-3-4fd7c7ff5815

I installed it fine, however I do not get the screen to Choose your environment as seen in the screenshots on the above articles.

I edited my preferences so that Environment is custom by default but still no go. I’m stuck with the defaults and no way to modify or change them

custom

Please advise.

The current version of Lightning beta does not include custom environments. They responded on Twitter saying that it should be coming this week.

Well I used the download button on the main page. Why the main download button is a beta product is beyond me.

Moved on to something else.
