Follow Me Feature? Max Til Vs. Max Tilt speed?


I am very new to this, I just got my bebop 2 skycontroller 2, I love it so far but have some questions I need to know the answers too before fully testing it out.

First, can someone please explain to me the difference betwenn Max tilt, and Max tilt speed? Aren’t they the same thing?

Also, I cant find the follow me app anywhere? Have they removed follow me or is it packaged into the flight plan app.
