As it says: when using shift+scroll (Mac, PL6 elite) the feather does not adjust as the tool tip says it should.
No problems for me (Mac M1 OS Monterey).
Are you using Mac OS Ventura?
In case of doubt, remember this feature only work with Brush, not with the others local adjustments tools…
Doens’t work using: MBP M1 Max, Monterery (latest update). Using the brush.
