(mac os sequoia 15.1) In photoshop version 2025 in the working document window the midpoint opacity, using the gradient from color to transparent, does not work... it only works in the palette window...
Can you show us a screen shot of your working file with all of the panels (Options Bar, Layers Panel, etc) visible so we can get a better understanding of the issue? Any additional information you can give us on the process you are using would also be very helpful.
