Home App / HomeKit has no remote access with iPhone 12 Pro on Verizon
I can control my accessories without any problem on Wi-Fi but can't access remotely (all shows No Response) with my iPhone 12 Pro on Verizon. However, my wife's iPhone XR has no such problem.
I double checked all the settings on the Home Hub (iPad) and my iPhone and found no issues.
It's almost the same issue with another Question asked but not answered here:

Thanks in advance for any help.
