Hello,
I observed an interesting bug in
https://nwm-trial.etsi.org/#/documents/4196
The very last feedback form (27) did not show any content, so I tried to refresh it. However clicking on refresh cause the text to jump up a page... so I could never click the button.
Solved the issue by hiding the comments plane and re-showing it.
Maybe there is an issue, if no p`aragraph is included after the very last feedback form?
