Carplay simply disappeared from my wife's profile. She needed to un-Ppair her phone and re-pair her phone for Carplay to come back. It could have been a fluke and unrelated to 2.4.4 update.
If you own and use a smart phone, you are by the default always a "tester" due to new features get added over-the-air. Likewise for most modern EVs, new features get added and pushed via OTA updates. It is what make owning an EV exciting.
After seeing the dashboard showing 14% complete, I stopped monitoring it periodically and went to sleep. Woke up this morning, the Lucid Mobile shows car updated successfully running 2.4.4. I haven't got into the car and take a look.

I use mobile key exclusively. Sure there were times that I wished mobile key responses quicker. As a backup, I have my key card with me in case either my phone die or run out of juice.
I don't understand the logic behind their OTA. It seems some Pure with DD basic received their update while Touring with DDPro haven't receive anything.
