I am constantly looking at documents rife with harsh red underlines because the spell checking software has a limited vocabulary. I want to turn it off but cannot find any current information on how to do so. Can someone tell me how this is done with the current (March 2018) version of the Xfinity interface?
You have to manually check spelling if you want to use it in the email software. What you are describing is not a product of the email program, but rather whatever browser you are using. You can enable or disable it depending on which one you are using. Firefox----Edge----Safari----Chrome?
