Thanks for taking time to reply gazumped and your suggestions. I was also happy to learn this is a "known problem" and not something unique to my situation. It's really confusing to see that permission has been removed for these notebooks, however they still appear in the shared section. I tried all the suggestions mentioned but unfortunately the issue STILL exists. The notebooks appear in the Shared with Me section and they receive you don't have access to this, which shows permission has been removed. But I still can NOT figure out why they continue to appear on the list in the shared section. This really defeats the purpose of sharing a notebook, why do this when the other person still sees information they no longer need.
I appreciate any additional thoughts or suggestions it would be great to resolve this issue.
