When you go to open the file chooser, the red error flashes saying the field is required.Asked by Imogenius13 on March 15, 2016 at 03:55 PM
This should only happen if navigating away from the file chooser.
I have tried to reproduce the issue using different browsers and operating systems, but there was no flashing warning on my side.
If the issue still persists, please provide us with a version of your browser and operating system.
