Oh Yes, fair observation!@jajo.j hi, I think for me the problem with touch regarding the back button in top left corner is connected with ios animation.
Can you check on your new device for me if you can quickly enter a dialog in messages and use arrow to quickly go back and continue several times? My phone (iOS 18.1) works ok if I do it slowler than the animation, but if I'm quicker then it does not register the touch no matter if the touch is on the back arrow or just in the middle of the name (to enter the dialog) like the Ios animation is disabling registering of any touch. I can easily reproduce my problem, but I have no idea if it is a problem with iOS or just my phone. Can you reproduce the problem?
PS. The diffrence between being too fast and just ok is very minimal, if I'm too fast I have to just tap slightly slower and it is ok.
as well I think that this your observation may be issue.
