i can jump to Photosho, edit photo, save photo, BUT when I jump back to Lightroom edited photo doesn't return. This is a recent action since Adobe upgraded Lightroom and Photosho. I have a Mac with latest upgrade.
Please check is your Photoshop is also updated to the latest update for camera raw.
Also, you may try and reset the Photoshop preferences back to default.
refer: Preferences in Photoshop
Resetting photoshop preferences worked, thank you.
