I'm familiar with using the suppress effect via the symbology pane in Pro. The effect works well for solid lines. However, if I add a dash effect to the same line, the suppress stops working entirely. Turn off the dash, and the suppress goes back to working. Is this an odd bug on my end or a known shortcoming of the suppress effect?
Edit: OK, after just posting this, I experimented with swapping the order of effects. Since the Dash effect is automatically added to new stroke layers, the Suppress effect was added after when I added it to the layer. I deleted the Dash effect and re-added it so it would be underneath the Suppress effect, and that worked. Odd!
