One of the fastest way for me to cull albums on Lightroom Classic, is the caps-lock "on" flagging feature. When Caps-Lock is on, you can just fly through the album by using "u", "p" and "x".
Also many of the keyboard shortcuts, such as + & - to adjust say "exposure" doesn't work at all in the Lightroom Cloud app.
Why isn't this implemented in the Lightroom Cloud, nor the Lightroom Web?
Also occasionally on apple m2, the arrow key to advance to next photo wont work until restart.
