I'm running Ubuntu 18.04 with the Frippery extensions which restore the classic top bar layout, task bar, menu and workspace switcher. Which works fine, except that Skype (8.28.0.41, installed from the repositories) doesn't show an indicator. Other applications (Knotes, Veracrypt, Amarok etc.) don't have this problem.

I've read about similar problems on 17.04 and 17.10 and several suggested solutions (such as installing sni-qt), none of which work on 18.04.

Does anyone else have this problem (i.e. is it a known Skype bug) or is it specific to my own install and do I need to look for the cause of the problem there?
