Hi!
The problem with autorotate is
people looking at the screen and wait until panorama rotating, then click at next pano and wait again
I'm making tours for realty agents and know about this a lot. (they call it video tour, hahahah)
I telling them "it's a virtual tour", the say "yes", and in next moment he call to client and say "we making video tour for you"
I'm tired of fighting with it
Only way is intro instruction.
