Since Catalina, option to export and to Use Lossy Compression doesn't seem to work no matter the camera raw compatibility?

It appears to be working for me Marko. What happens when you try? Error? Silent Failure? Something else?

I just discovered it works for me too, if I use the export preset I made before, but if one starts fresh from lr export presets, the tick box Use Lossy Compression doesnt seem to respond. Its probably just gui bug?

Hi Marco,

I am also able to reproduce this issue. Once I click on an Export Preset, I am not able to check "Use Lossy Compression". We will file a bug and investigate it further.

Thanks,
Chinoy
