2023 Audi S5 — a/C is cold on the highway but warm at stoplights

The A/C works well with road speed but gets noticeably warmer at long lights, then cools again almost immediately once moving. Does that point more toward airflow/fan behavior than refrigerant level? Interested in real owner experience more than guesses.
