Dear Alexandre:
Please check the following. Failing that please open a case
1) check in your browser's developer tools for any failed network requests. It might help point to a cause.
2) check the EM log for any errors related to retrieving the evidence from the APM Database.
3) See what happens if you click View In Map (top right)? Does your regular Map view have relationships populating?
4) check the IntroscopeEnterpriseManager.log and IntroscopeWebView.log, non APM DB related error information. Is there error information in IntroscopeEnterpriseManager.log during notebook access?
Thanks
Hal German
