My OneNote had gotten excruciatingly slow when typing. It took a second or two for each character. I searched and found nothing that worked, but it dawned on me tonight what the problem might be, and I wanted to share it in case someone else has the same problem. It was Grammarly doing it's spelling and grammar checking. I was using OneNote to track the activity on a project and didn't need any spell-checking. I'm guessing that Grammarly may also suffer a bit from disorganized content like this. I turned off Grammarly in OneNote, and immediately, I was back to typing at full speed.
