We have experienced the exact same problem, but our web developers came up with a simple solution.
In Illustrator: Use the "Export As" option. See screen cap for options selection.
Once exported, open the SVG file in a text editor (WordPad, TextEdit, etc.) and enter the following text at the very beginning.
<?xml version="1.0" encoding="utf-8"?>
That should do the trick. Good luck
