So my 2021 Sierra has the feature that if you press and hold the unlock button on the remote, it will open all 4 door windows which is a great idea. The problem is, is that you cannot roll them back up remotely. At least I haven't figured out how to do it. If its not possible, that's like giving us a 1/2 of a feature. Imagine being able to remote start your truck and NOT be able to turn it back off remotely. If there is no option to roll the windows back up, whatever engineer or whoever came up with this feature should have lost their job right on the spot. IMO.
