No adjustments slider previews for with new PS update

In the German version, most dialogs have the shortcut "v" to check/uncheck the preview. This important feature is missing in all new dialogs. This really needs to be more consistent! Very, very annoying.

Version Tahoe 26.0

Thanks, that took care of it. Wish they'd simply tell us, rather than wasting time with work-arounds 😉 

What version of macOS are you using?

If you go to Photoshop 2025>Settings>Technology Previews, uncheck Enable Modern User Interface, then restart Photoshop, does that make any difference?

@ML2travel they're working fine on my PC, Photoshop version 26.11 on Windows 11, have you tried manually resetting your Photoshop preferences

Remember to back up your settings before doing the preference reset
