As for the auto flip, I have tried it a couple of times but has failed but on both attempts, though this was user error.
You to set the mount to continue tracking when meridian is reached , forgot that last time and had it set to flip automatically, SGP got a little confused and took the plate solve image while the mount was still slewing.
It looks like it should work provided you setup the mount, there is a possibility of some clear tonight so this was something I was going to try.
From your question do I assume you are having some problems?
