I was using Lightroom Classic but decided to switch to Lightroom. What a mistake! Even though I have a very powerful machine (PC) the slow response of the software is just atrocious. I just don't understand how anybody can actually work with it. What's even more unbelievable and hard to comprehend is that the software is installed locally and the performance is so bad. I tried it on two different machines and I saw my colleagues working with it - it's just how this piece of software works. Badly. Adobe, please do something about it if you want users to switch from Classic to cloud-based Lightroom.
