I make a habit of going into the Chapter Languages setting and toggling it to All (none selected) and back to English for a quick check.
When there is a European language version (including South American Spanish) you can use Google Translate's image function if a manga you're following stops getting English translations. It's better than nothing except it's complete shit with Japanese because the language structure is so different, I guess. I'm using it for a manga I've followed for 3-1/2 years that hasn't had an English update in six months and was three or four months behind at that point.
