While I like EN the lack of some basic feature/function is confusing. Spell check is an example of a basic function available on text boxes for well over a decade, but missing on EN. A second strange area is on basic text formatting. It's easy to confuse EN if you use bullets of varying indent. It seems they're trying to branch out to other areas (e.g., work chat) that are unlikely to be successful at the expense of adding the fit and finish to make their core product first rate.
Thank you very much, Maya! EN suddenly changed languages on me and your note saved me tons of time and frustation. Of course, it'd be nice if EN would actually fix this and stop trying to be overly clever and automatically changing languages.
