Hi All,
I had massive issues with Notes app crashing on ios 11 - with all note stored on iCloud. It made the app unusable. And I am a heavy user with more than 5000 notes. I have been depressed for 3 months because of this!
There are many resources that try to help u fix the issue, such as (they all say the same thing):

NOTHING worked for me.
I have finally fixed the issue. Notes is now stable in ios 11 and the search function is fully usable.
You need a desktop version of notes + fast internet (if you have synced a lot of notes and attachments)
Firstly On your iphone / ipads:
1. Simply go to your iCloud Settings to view all the apps that are synced to your iCloud account.
2. From here, you need to disable the option for Notes.
3. As you will disable the Notes feature, you will get a prompt like this.
4. Tap on the “Delete from iPhone” option to confirm your choice.
5. Restart your device
Then on your desktop:
1) Open the app.
2) Click on icloud folder where all your notes are.
3) Control A: select all the notes in that folder
4) Right click your mouse - click Move to>On my Mac>Notes
All your notes will be moved from iCloud to your computer - Pls note that the Notes Desktop app froze (spinning ball) - DO NOT TRY TO QUIT AND RESTART. Just leave it. it is working to copy all note from iCloud to the computer.
If you are on slow lines leave overnight - should be done in the morning.
Then:
2) Click on Notes folder "on my Mac' where all your notes are.
3) Control A: select all the notes in that folder
4) Right click your mouse - click Move to>iCloud>Notes
As above - leave overnight. All your notes will be copied back to icloud.
Then turn on notes in icloud settings on all your mobile devices....
Smooth sailing....I am a happy puppy.
