Safari Web Clipper not working

Safari Web Clipper is not working for me. Every time I try to use the web clipper, it asks me to sign-in. I sign-in (using Google authentication), try again, and again it ask me to sign in. Notebook doesn't seem to keep me logged in. I asked about 3 weeks ago and no response.

Kishore, anybody? Is there anyway to get help with this problem?
