I have this same issue. Unfortunately, SnickZ seems to misunderstand the problem. The OP's issue relates to using Quick Notes with an Apple Pencil on an iPad when taking handwritten notes. It has nothing to do with formatting notes. Since I am also having this issue, let's try again.
To create the problem:
- Make certain you have the option "Resume Last Quick Note" set in the Setting for the iPad Notes app
- Open a Quick Note by dragging from the Bottom Corner.
- Take some handwritten notes with the Apple Pencil filling up the horizontal width of the Quick Note.
- Click Done to close the note.
- Drag the Quick Note open again from the Bottom Corner.
- You will now see that the display of the note has Zoomed to a larger size, cutting off much of the handwritten text.
You can see the problem clearly in the OP's posted picture, where a good portion of the handwriting in the Quick Note is cut off on the right hand side and is not visible or accessible.
The OP is asking how to resize the Quick Note so that the hidden text can be displayed. I have that same question.
Thanks for any assistance!
