thanks, airickess! That was it. I have no clue how that got changed, but I am suspicious that somehow the firmware update did it. Maybe that’s not even possible, though…
I should note that I did fully power down the mixer and stage box for a few minutes while troubleshooting and that didn’t seem to impact this behavior.
FYI, I had this same question. You need to go into “global filter” in the scenes manager and unblock the softkeys or soft rotaries to enable this function to actually work. seems to work like a charm once I have done this.
