It's amazing to me that users have kept gaslighting those who encountered the issue: "it's just warm. that's not overheating"; "it's indexing"; "you are using it too much"; "no issue with mine"; "first world problems"; "just be grateful"...on and on and on. The issue is with Apple's end all along. Even Apple admits it. Next time, just accept that some people might have problems with their devices that might not be happening to yours, and that the problem could be with Apple and not the users. You can believe other people's complaints and still be happy with your own device. Don't take it personally.
I DO believe other people ARE having issues with their devices.
The issue COULD be with certain apps and how they are programmed. Net time, just accept that some people might not have problems with their devices even though they are happening to yours, and that the problem could be with the programmers and developers of 3rd party apps, and not Apple. You can accept that some people had no complaints with their devices, even though you did. Don't take it personally.
As for me, I had no issues with my 15PM. That doesn't mean other people have or have not had issues with it, and it doesn't mean any particular issues is at "fault". It just means something somewhere went wrong and it needs fixing.
Which apparently, was addressed in a timely manor.
