The web clipper on Safari is no longer clipping articles for me. I have encountered this problem with Amazon.com, Tcrecord.org, newyorker.com, and many others. The floating description of the clipper when I hover over it is "Sign into Web Clipper" even when used multiple times so it should be signed in already. I use Safari Version 10.1.2 (12603.3.8) on a machine running Mac OS Sierra 10.12.6.
