A couple of days ago I upgraded from UM 19.04 to 19.10, and I was pleased to see the new notifications applet and indicators area in the panel. At some point, however, the new features have been replaced by what looks like old (19.04) behavior. Attached is a picture showing the current state and the fact that the "Indicator Applet Complete" is version 1.22.1.
It is not clear what I have done to cause the regression. I wonder if anyone can suggest how to reinstate the 19.10 indicators and notifications applet?
