Following install of iOS 18 notes is lagging significantly. All other app improvements are working well. No other issues.

Re-opening and closing the app (at least 20 times) didn’t work for me. It kept freezing whenever I tried to open any Note. I eventually figured out that the problem was caused by my having one particularly large Note (over 35MB including embedded photos). I finally got that Note to open in the Cloud by waiting several minutes. I then spent several more minutes trimming it down. Then Notes started working okay.

Frustrating that I lost the vast majority of that Note (I couldn’t Share it anywhere; Notes would just freeze). But at least I can now use Notes again.

Apple clearly did not user-test iOS 18 with a large Note!!! 😡

My notes began to lag horribly and I’ve finally realised it could not handle the “*” asterisk I had started using for bulletpoints… I think it was trying to read every single one in some way to understand them as unformatted bullets with the potential to be made into bullets.

(if I put a space next to them they would become a genuine bullet)

I quickly did a find/replace in indesign to turn every bullet/asterisk (about 500) into a less troublesome symbol (e.g “>”) and my notes are now as quick to use as they always used to be. I hope this helps someone as it was driving me crazy!
