I'm wanting to update my avatar to a new actual picture (I've lost weight!) but after I select the file and try to update, the button just stays darkened and it never updates.  Any idea what might be going wrong?  It's a plain old small .jpeg, just like the previous one.
 

Scratch that.  Worked with Chrome.  Did not work with Safari.  Maybe an issue with the javascript differences between the browsers?  This is on a Mac running Mojave 10.14.6 if it matters.  Chrome Version 76.0.3809.100 (Official Build) (64-bit).  Safari Version 12.1.2 (14607.3.9).
