Cursor jumping to the end of a note as I’m typing

What I did: Typed in the middle of a note, as one does.

What happened: The cursor jumped to the end as I was typing, so what I was writing ended up a weird fragment at the bottom of the note instead of where it belongs.

What I expected: For this to not keep happening. This kills my focus every time and mangles what I was working on. It’s also been happening for months now, off and on. I’ve been told it has something to do with syncing but quite frankly unless it’s caused something I can set up differently on my end, I don’t care what it has to do with — I just want it to stop happening.

Things that might be helpful to know (Agenda version, OS and model, etc): Mojave 10.14.6, Agenda 6.0.1.

I’ve seen this a few times myself, but it is difficult to track down, because it is not really reproducible. If you do find a way to “trigger” it, please let me know.
