I think he's referring to the mobile quick guide which is launched from the blue hot key. When you open that only Explorer and Anywhere are displayed. I checked on S3.16 and S.401 and it isn't there on either. But again, I never paid attention to that so I'm not certain.
It was there but isn't anymore. I remember using it to show a customer how the transfer works about 2 weeks ago. It was basically a set of instructions on how to do the transfer to an iPad.
This was a nice set of instructions for people to reference for a step by step for the transfers. It was nice while it was there and it's apparently gone. I think the OP was just looking to see if anybody else noticed or knew why it was gone.
Maybe they're getting ready to release the Android transfer and are redoing the app.
