I’ve been frustrated with this, too. I can’t believe a trillion dollar company has us out here, grubbing around for answers to basic UI questions.
Here’s what’s probably happening:
Apple Notes seems to block content types (handwritten vs. text) in rows. So if you have a handwritten note, and want to add text, you must scroll to the bottom of the handwritten section, then click to create a cursor. Then you can type.
This is related to the insane friction Apple put in front of just changing the name of a handwritten Note. The basic directions, to change a name, are to “pull down on the note.” But if the Note is handwritten, THIS DOESN’T WORK.
All the quickie, simplistic responses in the “Community” say, “pull down to edit the name!” But this only seems to work if the Note has a typed text section. So to change the name you must scroll to a new section (usually the bottom), click to add text, and then the title change option appears. Alternately you can paste text over the handwritten section - then the “Aa” button is enabled.
It’s a really sad state of affairs. I imagine some rational UI designers have quit Apple over some ancient belief that this is a good user flow.
Maybe allow us to RIGHT-CLICK on the title like every other app on the planet?
