Only GNOME extension and native icons are displayed. Other icons like Dropbox, shutter, enpass etc. do not appear in the top bar.
Am I missing something? I already tried using extensions that I used with GNOME before but nothing (Topicons Plus, Ubuntu appindicators etc.) seems to help.
Currently I'm using Ubuntu Xorg, but in Wayland I have the same issue.

I've encountered the same problem. I tried to remove the indicator-application-service completely, and see, the problem went away! I guess coming from 16.04 leaves some Unity-related stuff on my machine that is not only obsolete but prevents the AppIndicator extension from properly working.
