In the last few days, LR Classic CC is acting weird. I have the latest update. When I open it and go to a folder it often shows gray tiles in the Library module, grid mode. There should be images there. Sometimes I can re-start the program and it will work, but most often nothing. I need to get some editing done, Adobe! I have purged cache files and my computer is pretty fast. Everything worked fine till i did the latest update around 8/25. Anybody got a solution?
