Issue: Unable to see participant name list in large meetings.
The full participant list isn't available for large meetings.
This is expected result whenever you join large meeting were participants are more than 75 participants.
In the Participant list side of the conference window you will show the number of joined participants in the meeting. However participants name will not show.
This is expected result. You may check QoE and CDR report for full participant list.
The above change in user experience is directly related to large meeting. I have not seen this were number of participants are less than 75 in meeting. Assuming that this experience shows only number of participants are more than 75 meeting.
