How do l disable email from scrolling up when I open mailbox on iPhone 15?

Also didn't work for me - I have the same problem and if I use another app for my emails this doesn't happen so it is Apple mail specific.

Go to Settings > Accessibility > Touch, then tap Haptic Touch or 3D & Haptic Touch. Choose the touch duration—Fast or Slow. On an iPhone with 3D Touch, you can also choose the pressure needed—Light, Medium, or Firm.

I am also having the same problem for iPhone 14; as soon as I open "inbox", emails start scrolling fast automatically and does not stop. I can't read any email. If anyone knows how to solve it, please help!

Me to - scrolls quickly to bottom. Can’t go up to read other emails??
