Unable to remove yellow banner

Operating system

Windows

Joplin version

2.14.20

What issue do you have?

I attached a PDF but it was not possible. I then deleted the PDF but the yellow banner warning remains. How to remove it please?

I'll answer my own question here. After looking around, on the desktop version go to TOOLS then NOTE ATTACHMENTS. Find the PDF you previously attached and DELETE it . This will remove the yellow banner warning.
