Could you please confirm if you are editing raw images in Lightroom or jpeg images?
Is the workflow of Lightroom adjustments stored in Photoshop common for specific file types?
Also, perform the below steps :
1. Go to Lightroom Preferences > External Editing > click on choose next to Additional External Editor and choose Photoshop Application.
2. Choose any image and press Command+ Option+ E to choose Edit in Photoshop
I USe RAW FILES with Lightroom , Sometimes The pictures Lightroom Changes stay when i make CMD E and go in Photoshop
Sometimes , Change not stay when i go in Photoshop
Still continue to choose it even if it already exists and it should allow you to choose.
nothing change ...
Would suggest you to create a new catalog and import a few images for test and check if that works well when you choose edit in Photoshop.
