I use the the Copy Shape Attributes/Copy Shape Fill to duplicate my gradients to other shapes. These past 2 months, sometimes the feature works while most times it doesn't. Shutting off and turning on photoshop doesn't solve it. The Copy Attributes/Fill Option is available and clickable (it isn't greyed out) but the paste feature is not. I just repeat my attributes manually instead but the issue is a hassle.
I'm not sure if I am doing something wrong or if it is a bug.
