I just switched from Desktop to Pro and cannot figure out how to get the swipe function to work. I have multiple raster layers and want to swipe between them. Among other new features/procedures, I have figured out that many functions depend on which layer is selected in the Contents window, so I thought that if I clicked a raster layer (that is currently visible), then went to the Appearance Tab, I would be able to select Swipe, and swipe away the selected layer. I also remember being able to do this with vector layers, which makes sense because the functionality isn't raster-specific. However, I the Swipe button is always grayed out and I cannot figure it out. This seems like a basic growing pain of switching from Desktop to Pro - that list seems to be endless. Thank you in advance for the help!
