Notes app is crashing after iOS 18 update on my iPhone

Same issue here on IPad Pro M2, large lecture notes with pure text are fine (mostly). Turned off ICloud sync which kind of helped. While taking notes with lots of math and calculations Notes tend to crash. Personally found two workarounds:

1. Turn off wifi, sometimes the devices such as your Mac or iPhone tend to contact your device for what kind of app is open. Using your device offline can pro long battery life and also prevents notes crash.
2. For large notes on IOS18 try using calculator notes section to write all the notes for whatever relevant topic. When you are done go to Apple notes and move the note you just wrote into desirable sections.

these are my personal tricks that helped, I hope this will be patched in next updates.

Having the same issue on ipad m4 13inch ....its really frustrating.

Mine one is iPhone 14, Notes problem happened after updating iOS 18. Please answer someone who knows how to fix it!

Same here! 😡

Hi Metis, I just replied to you but it seems my post is lost or at least I can’t see it, so I’ll try again.

Thank you so much for the reassurances. You’re right. I followed the steps and eventually all my notes came back! 

It doesn’t solve the problem: when I first open Notes, my iPad screen is blank except for two tiny arrows in the upper left screen. I tap on those and then get a screen saying no notes. But there’s an icon in the upper left corner so I tap on that and then my Notes folder page appears.  Before the iOS 18 update Notes automatically opened up the actual Note I was previously working/writing in.  I did update to iOS 18.1 today - didn’t make a difference.

No. Ive done this over a dozen times already. Doesn’t work.

The web version doesn’t let me copy the notes. Just select. What’s the point in selecting if you can’t copy or cut?

My notes jams after installing latest software

Is anyone else seeing Apple removing comments here, mine has been removed twice.

Neat and cheers for letting me know - I was referring to 18.0.1. I wonder if this fixes the freezing and lagging? Going to update and report back.

It is still just as slow and laggy as the original 18 release. So frustrating. I wish apple would fix their notes app!

Does not work

Renew my finding of this bug:

As I mentioned previously, I found out that condition only happened while the "text format" window open. If I close the "text format" window, nothing happens no matter how many words I "look up."

I found the similar bug while I use the Journal app, the only difference is it will not crash Journal out directly, just the "look up" result could not display normally and close immediately.

On iPad OS I started out with very similar issues but my machine 11 inch m2 was next to my 10.2 inch machine which was updated properly (yea) and worked itself out over the next 24 hours not sure what I did but Apple must have built into their programming this type of help and backed up and updated my 11 inch air so it would appropriately download IOS 18. Previous attempts at recent backups and IPad OS 18 downloads were unsuccessful on my 11 inch air m2 most likely because I needed to pay closer attention to what was going on. Any way iPads work but IPhone is frozen and needs help beyond my ability. Probably a software issue, but may have been caused by not backing up properly and waiting patiently so as we say in the IT world arrg! I think what I am trying to convey is I could have saved a whole lot of issues by reading through the documentation first, properly backing up my devices and downloading the new IOS or OS afterwards. Very sorry for the novel. It may seem like a great deal to remember but it can save more time in the long run.

I let my phone power down and powered it back up through my Mac Air it took a bit. When the phone powered on all the apps were restored and I could use the phone again without any messages from Apple that this phone is lost or stolen. And being able to use the touch screen had been restored too.
