Im actually a skeet shooter also, 3 TN state titles in it. I still have no software update from GM, I wonder if it was a gas only update, or maybe a Denali only update, who knows, Im still using mine with the rubber pad off and its working pretty good.

Congrats On the titles. I'm just a league shooter but have a great time doing it. Looking at the first improvement has to do with SuperCruise That's Denali and High Country so you maybe right about Denali. The two enhancements I have seen are the wireless charger and the Automatic headlights seem to come on earlier. When I first picked up the truck the auto headlights didn't light until it was really dark. Hang in there Kevin I'm sure its coming soon.

I have the same issue. 23 high country, iPhone 12/14. Ridiculous that something so simple and they can’t get this right. My 20 high country worked flawlessly with the iPhone 12.

I have the 2022 refresh and the wireless charger would not work with any of my phones. Samsungs. It would charge for a few seconds then shut off and back on until it cycled to a red exclamation point. Both with and without cases, inserted in multiple positions and orientations. I spoke to my salesman who asked someone in the service department about it and he found out there is a GM Service Bulletin regarding the wireless charger in the new trucks. There are 3 versions of it. The first version does not work with many phones including all Samsung and must be replaced with the newest version of the module. The second is the correct hardware but requires a firmware update to work correctly and the third is the most current version that works as advertised. I brought the truck in and mine had to be re-flashed with new firmware and it now works PERFECTLY with all my phones.

Is there a way to see what version firmware we currently have or did the dealer need to plug in to tell?

Dealer has to use computer to get firmware version. The hardware version number is on the module I am told, but its on the bottom so it must be removed to see what version it is.
