I cannot log out from the app because one note does not synchronize

I'm getting this message, and there is just one note with the sync icon on it as if it doesn't synchronize. But when I log from a different device it's there though. How can I fix it? I've edited it to see if that would change anything, but it doesn't.

You cannot log out from the app while synchronisation is in progress. Please try when it is completed.
