I checked the same on my end, it is also not working, I am working on a Windows computer.
Let me check with the team and I will update you regarding the same.
Thanks Jim. Opening Preferences and closing again worked. Scrolling is fine now.
I can scroll through images, BUT not up and down the side panels.
Could you please let me know the exact version of Photoshop installed on your computer?
Also which operating system are you working on, Windows or MAC?
If you want to scroll up and down in the side panels, you need to click on the side panel first and then you will be able to scroll.
