Received my iPhone 14 Pro about 3 hours ago. Here are some quick notes:
I transitioned from a physical SIM phone to this eSIM phone on AT&T. The process went smoothly. Everything was quite automatic with very little input needed from me.
Note that transferring to eSIM on ATT was smooth but it might take a little time. I don't know how long it took because the phone was doing a data transfer in the background and I am not sure at what point the SIM transfer was completed.
I opted to do data transfer from phone to phone (instead of from iCloud or Mac backup). Everything went smoothly and the transfer was very complete. All settings and apps were transferred (I understand that the apps and photos were re-downloaded).
I have not bought a new iPhone for a while and was prepared for a long hard setup, but the transfer was so smooth and complete that it was a little anti-climatic. Even most of my apps on the new phone remained signed in.
Enjoying the AOD just as much as I expected.
The dynamic notch works well. Very convenient for playing music.
One thing I did not expect was that I sometimes watch some videos in PiP but I don't really need the video to be constantly on screen. I just want quick access to it. By disabling PiP the audio goes to dynamic notch instead (but only if the app allows background audio without PiP), and so not only do I have access, but the screen is not covered by a video that I do not need to see (I know you can swipe video to the side so it becomes a tab, but the dynamic notch works even better for this. I would prefer if swiping video to the side hands audio off to the notch.)
One glitch unrelated to Apple or the iPhone is that I am unable to set up Apple Pay with Chase at this time. Twitter seems to say that this is an issue with Chase. I expect it to work later. (Update: Resolved)
Hope this helps some people. I might add more notes to this if something occurs to me.
