My text expansion snippets suddenly stopped working in some apps but not others. When I invoke an abbreviation in Word or Excel, it works. When I try using the same abbreviation in Mail or Drafts, it doesn’t. It doesn’t matter if I use Rocket Typist, Text Expander 5, or Alfred. It doesn’t matter if the abbreviation starts with a “;” or an “x” — I type it, the abbreviation itself flashes on to the screen, and then … nothing.
