When you choose to notify clients or instructors about a class edit, the old and
new instructor names in Email, SMS and Push follow your venue's public schedule
name setting: full name, first name or nickname. A venue-only schedule name takes
priority. The same applies when a substitute replaces an instructor.

SMS now says, for example, “instructor changed from Signe to Shahab” instead of
using symbols that some phones display as question marks. Notification choices,
recipients and delivery preferences are unchanged.
