This may be due to ‘in-progress’ + ‘failed to classify – after classification timeout’ sessions.
It’s ideal to show only the ‘failed to classify’ session as ‘Incomplete’; since we can’t find any equivalent ‘app-id’ as part of DPI-Vendor supported app-list, we went ahead with ‘Incomplete’ for ‘in-progress’ sessions.
Our engineering team will try to enhance this further to show ‘incomplete’ only for ‘failed to classify’ session.
