Edit: I found this online: Starting in iOS 15, Apple allowed you to tag certain items, like Reminders and Notes, with hashtags (#). This way you could more easily search for items without having to necessarily remember the right words. So you can tag all the recipes in your Notes with things like #Vegetarian, #Chocolate, etc. to organize them and make them more searchable.
This comes at the cost of locking those notes. Locking a note makes it completely unsearchable except for the title, which defeats the purpose of adding a hashtag intended to make a note more searchable. If you can’t lock a note, check to see if it has any hashtags in it and delete said hashtags. Unless your note has another offending item that prevents it from being locked (see below), then you should now have the option to lock the note.
My note does have the # sign - like ID #12345 or SSN #123-45-6789. So that must be the problem: Apple is interpreting this as a hashtag!
STOOPID APPLE!!! Please fix this and allow us to put ANY characters in our notes!!!
Does anyone have work around?
Thanks
