For the last couple of months every time I try to use a directory style upload (drill down or just go to desktop and see files) I've started getting huge delays where it takes up to 10-20 seconds to be able to click or select an item (even cancel) Example – upload a photo to Facebook. You would normally just click a couple times quickly and it's done – instead it might take me 3 minutes to accomplish the same thing, getting stuck at each directory level.
I've tested this in Chrome and Opera and it's not a problem.
I've disabled all extensions and no help. Any ideas? Safari Version 13.0.3 Mojave 10.14.6 2019 IMac 3.7 GHz 64GB
