Hello,
When my friend try to clone the workspace or try to sync local change
An error say he need Head perm
Here a screen of the message my friend got
Plus another error on the issue we can choose 2020.2 versions (and the versions is not released so)
Issue comments
I suggest you to wait a week or two, we are working on tutorial series for this.
But in short, pull change should pull changes from the remote workspace, but you need to sync your changes to the remote workspace first.
And avoid working on the same elements at the same time.
Please provide the URL of the workspace he is trying to clone.
And if possible, a screen recording of clone attempt.
