My car was also delivered with 2021.3.103 on 6/21.Haha, I wish there was a way to force the update. Unfortunately I'm still stuck on 2021.3.103...the version my car was delivered with on 6/24.
I first noticed the software update in the app today around 5PM. I immediately kicked it off.
Hopefully you have the update by now, or will get it very soon.
