The new layer blend modes in ArcPro 2.7.x are great - to a degree.
According to the ArcPro Help:
"Layer blending draws the entire layer and blends it with the content below it in the drawing order"
I understand this to mean that if you enable layer blending on a layer, then the blend affects that layer and all the others below that layer, as listed in the Contents pane.
However, when I enable a blend mode on a layer, it affects every layer in my layout. As a result, all of my other layers that are above the blend-enabled raster disappear. The only way to show the other layers in the layout is to then enable a blend mode for them. In other words, if you enable a blend mode on just one layer, you have to enable a blend mode for every single layer if you want it to appear in your layout. And for every situation I have encountered, when try all the various blend modes for all of my layers, I can never get all my layers symbolized the way I want.
So my question is, am I wrong in thinking that blending should affect only your chosen layer and those below it, as is stated in the ArcPro Help? Or am I just totally missing/misunderstanding the logic of layer blending?
