The feature definitely wasn't removed, and it's still working perfectly for me. I haven't been able to see a use case in which it won't work, at least using Chrome or Firefox as my browser. Have you tried the usual clear cache, clear history, start new session tricks? How about incognito or private browsing mode in Chrome and Firefox respectively?
If none of those change the outcome then I think that you'll probably want to open a support case. Hope that helps.
