Android Profiler

So in the newer versions of Android Studio (I’m using 3.1.4), the Allocation Tracker has been replaced by the Android Profiler. My problem is that the Profiler panel contains nothing. It’s just an empty grey area. The documentation suggests that it should contain something. Anyone else having the same problem or am I just special?

Answering my own question… I discovered if I undocked the Profiler window (Gear wheel icon on the Profiler caption, select Windowed Mode) that the Profiler then populated itself correctly.
