What issue do you have?

I was in the middle of editing a note, when the entire content disappeared.

I have tried Ctrl Y but nothing came back. Is there any way to restore this?

Other notes are just fine, this was a rather large note, I don't know if there a size limit.
I had just upgraded a few minutes earlier if that helps

Thank
Dave

Never mind, I found how to restore from history, thanks
