It seems that the problem persists for our site. Surprisingly, I was properly redirected to one content section and wasn’t - to the other one.
The x-nf-request-id header I managed to find is the following: 764f556d-e183-4914-a063-8b701bbd4aa7
I am, however, not sure I have selected the proper request, as I don’t know which request should I look for in case of redirects made by netlify. From the available at the console at the moment I tried to access the content section I have issues with, the only one making sense was the one named netlify-identity-widget.js
