I just installed the stand alone version of Lightroom 6 and when I open it I am missing a slideshow and new photos found in Lightroom 5.
What to do ?
Installing Lightroom 6 doesn't cause any of these things to happen.
Did you choose to have LR 6 upgrade your Lightroom 5 catalog? That could cause the problem if you selected the wrong Lightroom 5 catalog.
