Unable to wake car on iPhone 12 – Tesla Review

When using iPhone 12 Pro on cellular 5G the car will not wake from sleep. If the car is already awake it connects fine. If the car is asleep it results in a network timeout. On WiFi it works perfectly. I have confirmed the cellular data setting is on for the Tesla app. There is no Tesla app support available it seems to report this.
