Hello, I have since 26.09.22 the IPhone 14 Pro Max and the stuttering when closing various apps I had 1 day later, I wrote to Apple support and I was advised that I should set up the Iphone as a new Iphone what I did, after 1 day again exactly the same, have it set up so far 5 times as a new Iphone and 3 times with a backup reset. I have written very much with the Apple asupport, phoned and it could never be said to what it is. I have always said that it must be a memory problem but I have never been taken seriously. Yesterday I was in the Apple Store Vienna (Austria) and told everything at the Genius Bar and he said: After the reset everything should work again but if I want it will be sent in. An answer where I felt as a customer again not taken seriously. I can on Saturday again to the Apple Store and then we look at what was done and will report back here. It is really the first IPhone with this problem, and that since IOS 16. Greetings Robert
