Hello,
I am facing this problem in both my staging and prod websites.
The progress bar throws a null ref when trying to change any value.
In the staging website, it was pre-activated, so it hangs when I change any value.
In prod, I had deactivated it myself and tried to reactivate it. It gets activated but throws the same error. Also, I don’t see the popup to edit the progress bar. The website gets greyed out.
All the screenshots are here:
