I tried creating a new project, using the Package Manager, +, Github as instructed, however, I get the following error:

[Package Manager Window] Error adding package: https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi.git?path=/com.unity.multiplayer.mlapi#0.1.0.
UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()

I may be worthwhile to add this error and its resolution to this page, just in case anyone else hits it. I don't know what the resolution is or what this means.

@JustinMinnaar can you let me know if you copied using the copy button or copy via select all method? we have seen this reported in Discord that there can be a hidden HTML artefact space( thats not in the actual source). we will investigate this

There doesn't appear to be any whitespace in the HTML generated.
<div class="token-line" style="color:#bfc7d5"><span class="token plain">https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi.git?path=/com.unity.multiplayer.mlapi#0.1.0</span></div>

Not sure if we should try adding some whitespace stripping CSS to the style.

I propose adding a Guidance admonition as below

We recommend that you use the 'Copy' function in the code block above to copy the URL as other methods may result in errors.

This is the proposed update

Completed, this change will be live today. We are also updating the CSS to make the copy button brighter, easier to see!
