Cannot upload image file for favicon


I am trying to add a favicon to my app but the "Upload " icon/link in the “Settings/General/General appearance” section does nothing when I click it.

I expected that it would open a file browser dialogue box to enable me to select an image file from my computer, but nothing happens.

Can you please tell me what to do about this?

Kind regards,

Francis Burns

SOLVED. I was using Chrome on a MacBook. I switched to Firefox and the file upload functionality behaved as I expected.
