On one of our servers we're running build 140422. I have it set to send a detailed email notification when a user completes the survey. The feature works as expected, however the formatting in the email is bad. Everything is crammed together and is difficult to read.
However, we have an older version running (build 131206), and when it sends out a detailed email notification of a completed survey, the formatting is just fine and very readable (appropriate headers, tables, etc.)
