Note is unavailable

Why is the reason that appears this message? 

I have the internet service open and good. 

Even check with wifi or hotspot

Hi.  No clue why that note should be 'unavailable',  but it does seem to be shared with others and the subject of active chat - it may be that it's locked because someone else has access to it?
