OK, what you said about Chrome isn't correct, at least not for me.
My version of Chrome is 50.0.2661.102 m. It does not have the option "“Use this language for spell checking”
Mine has the option "Use a web service to help resolve spelling errors" and this was already checked.
Automatic Spell check in my Xfinity Connect email simply does not work. I must manually click the Spell check button to get my email checked.
As a matter of fact, when typing into this message an incorrect word, the automatic spell check also doesn't work.
For those that have brought it up, Spell Check is built in and enabled by default in all modern browsers. As a core functionality of the browser, a separate spell check feature within the webmail is redundant and uses resources best spent elsewhere.
In short, spell check SHOULD be working for everyone. Please investigate your browser or browser add ons for any spell check features
If you don't feel your spell check is working, you can attempt to disable and re-enable it.
Enable spell checking in Chrome
Click on the menu icon on the top right of Chrome toolbar, choose “Settings”
Scroll down to “Show advanced settings…”
Click Language and input settings…
Then make sure that “Use this language for spell checking” is checked
