@jayoshih I still experience this issue at: https://studio.learningequality.org/
The loader/spinner still goes gray after a few seconds of initialization

Wondering if we should just not track the progress in the frontend and just show the indefinite loader? @jtamiace - seems like the lack of progress can seems like an error to the user.

@rtibbles while testing #3044 I checked this one as well and I can confirm that it's not fixed - this is still happening at https://hotfixes.studio.learningequality.org/ as described above.
