It appears that Speed Review is missing from the July 18, 2017 (2.8.0) release of Lr Mobile for iPad. I know it was dropped and then brought back with the Rate & Review mode on the iPhone. Is the intention to do the same for the iPad? If not, please consider this a request to bring it back...and the sooner, the better! It's a great time saver when culling and something I use and teach folks about regularly.
