Today we made a tiny change just to the wording of Scheduling Preferences on profiles. It used to use the word "times", as in how many times per month someone prefers to be scheduled.
Today we changed this word to the word "plans". The functionality was always related to specific plans, not times within them, so that hasn't changed. But especially if you use Split Teams and schedule people to specific times within a plan, changing the preference wording to "plans" makes it clearer that the preference is for the entire plan, not just times within them.
