I took a few photos and even a 30 second video, and had zero issues. Just be smart about it. Be quick, don’t have your phone out the whole show, probably don’t record entire songs. A couple pics here and there, and you should be fine.
I think the official policy is “no” but enforcement is highly dependent on the venue. I heard the Ordway staff say no when someone asked, but they seemed chill and it didn’t appear to be enforced. (Compared to the Astonishing, which was at a different venue, where it was DEFINITELY enforced)
I was a few rows from the stage and the guy in front of me practically stuck his cell phone cam right in JP’s face and he actually smiled and gave a nod for the camera, so he didn’t seem to mind that much lol
