Windows will not go up, or down from the app

Question

21' Audi SQ5 - Evo-One with Remote Start and Thar-AUD2 Harness.

The windows will not go up or down from the app. The app say Aux5 should put the windows up, and Aux6 should put the windows down.  When pressing function Aux5 on the app, it says "Windows Closed", but nothing happens. When pressing function Aux6 on the app, it says "Aux6 Command Sent" and makes a sound of the windows going down, but nothing happens to the car.
