Navigator goes blank after Utah upgrade

[MS12]

 As title mentions, while using the fulfiller portal the left side application navigator goes blank. If you refresh or click on any of the menu items (All, Favorites etc) it comes back. Has anyone experienced this? Cannot find any know issues or community posts regarding this.

You can pin All menu if you want to see left navigation menu always. This is how it works in Next experience UI introduced from SanDiego release.

Thanks Swapna. I'm aware of that but that's not my issue.

We are experiencing this same issue after our recent Utah upgrade as well.
