I enabled the Note tool in my Org and I added the relative related lists in Objects Layout. The problem is when I switch in Lightning Experience I can't take the note but only attach file. How Can I take Note in Lightning Experience?

clicking on it will open a popup:
And saving this will add your note.
Keep in mind that for displaying the button in your record home, you need to edit your page layout, choose
Salesforce1 and Lightning Actions and drag and drop the
New Note button to the
Salesforce1 and Lightning Experience Actions area:
