It was 100+ for most of yesterday and the car was parked in the sun for most of it. I drove about 27 miles on the highway and only halfway through the trip did it feel like the car was cooled adequately. This was on Auto Lo, so I let the car figure it out as I drove and it took about the halfway point of each way to get cold.
It wasn't uncomfortable, so it was cooling a little bit but it certainly was not as good as our other cars. But I also can't remember the last time I drove in 100 degree heat.

I’ve noticed that when temps are in the 90s and my vehicle has been sitting in the sun, that my AC doesn’t seem to be cooling well enough and takes a while to cool down. I have 2017 with dark blue exterior and brown nuuget(so) interior. Max AC seems to be not as cold as if I just have on 62. Cold air is coming out of the vents and maybe this is normal but just seems like it isn’t cooling as well as other vehicles I’ve owned in the past. When i leave a garage on hot day then it works fine, so maybe just a matter of sitting in the sun. Anyone else noticed this?

Mine has a Max AC button on the right side of the climate control panel, and when I push it the temp control dials show "Auto Lo."

My bad, thought we were meaning low temp vs low fan. The BMW Connect app did have one useful feature compared to MMI Connect: you could program the vent fans remotely to come on and vent the car prior to leaving work or shopping. Even without the AC, this could significantly reduce the heat load in the car.

In BMW you can set Auto (which I like) but then you can set the fan speed for Auto using the fan toggle switches. Is there such a think in the Audi? I like to leave my temp set with Auto, but would love to lower the fan speed because the Q really blows a lot of air. Any way to adjust that fan speed while staying in Auto mode?

Completely agree - I didn't do the windshield, but did a ceramic tint on the sunroof, which made a noticeable difference in interior temp (gray Q7 with black interior). It's not super dark, but has reflective properties to reduce UV, etc...

Do you mean IR? I would have hoped that the stock glass would be ~100% UV blocking, to protect occupants from sunburn, and the interior materials from bleaching in the sun.

Hmmm....I think you're right. But if the stock glass doesn't block all UV, the tint does. LOL
