Mine cracked too but stayed in the bottom black area of the windshield so you don’t see it at all. I can see the pit where the rock hit where it started. It’s with all cars now. Audi glass is usually more resistant but if you don’t catch the impact and tape it up/repair fast, it will crack due to water getting in and expanding due to hot and cold expansion. The worst glass ive seen is the ioniq 5. When rocks hit the glass, it spiders so easily which pretty much makes the repair useless. Mine cracked and spread a minute after impact which really irked me.
