When you are starting a new project in collaborate in 2020.1.0a14, clicking 'Start Now!' will do nothing.
A blue bar moves around for a moment and then stops.

1. Create a new project.
2. Click the collab dropdown and select 'Start now!'.

Expected result: Services window is opened ready for setting up your collaborate project.
Actual result: Nothing happens.

Reproducible in 2020.1.0a14
Not reproducible in 2020.1.0a13, 2019.3.0b12, 2018.3.13f1, 2017.4.34f1

Note:
- Tested on three different computers, two windows machines and a mac.
- Tested package versions 1.2.16 and preview.17 - 2.0.0, appears to be affected by unity version rather than package version.
- Even if you have the services window open in editor, nothing will happen.
- Looks like the 'Create a Unity Project ID' we used to see appear in the Services window has moved to the Player Settings.
