Android Status Bar Icon

[Dan Friedman]

Greetings!   I am seeing inconsistent results on the status bar icon on Android.  On some devices (most running Android 9), the icon that appears in a push message is a white or grey square.  I have tried using a 24x24 PNG for the Status Bar Icon and I also tried a 512x512.   Another device running Android 10, displays the image just fine (at either size).  Is there an image size that I should be using?  Or are there incompatibility with LC and Android 9?

Anyone have any insight to this issue?
