This is the iPad version of Lightroom. The translucent shadow on the right side didn't exist before, I mean the semi-transparent shadow on the right side disappears when the finger pulls the bar left and right - in the previous version. Yesterday I found out that my Lightroom was upgraded (I started the app auto-upgrade). Then I found that my iPhone’s version of Lightroom was also upgraded and it had the same problem with iPad’s version and then after a few hours suddenly the shadow on the iPhone’s version was gone.. Is there something I don't know about....? This has seriously affected my work... The following are the ipad and iPhone versions, thank you very much! !
