Just checked and it’s indeed “Desktop View” and when I switched to “Mobile View” layout changed, etc. and profile info was loading fine. Earlier by “Desktop mode” I tested “Desktop Site” on the web-browser itself rather than changing it on Forum level.
Query is, can we tweak CSS of that “Desktop View” which fixes the issue when it’s in mobile-responsive mode? If it’s too much trouble then I will try getting used to “Mobile View” mode.
