This issue has been persisting since Monday.
I have been running some online seminars since the 14th September and have not had this issue once.
Since Monday 28th September I have had presenters, delegates and myself as the host face this issue.
Having checked the reports on one of the seminars, I can see that the presenter has a 'Time In' but no time out. Every subsequent attempt to join results in this 'Another connection with this ticket is already in progress' message. They still seem to be hanging in the room taking up an attendee space while not actually being connected.
Can anyone advise on whats causing this issue or a fix.
We are experiancing the same issue. We have opened a ticket with our contacts and they said they are reaching out to Adobe. We don't have a response and this has been going on for over a week now. We are having issues with people coming in via our registration link and then we have to give them the presenter link to get it. This doesn't work as it causes alot more back end reporting. that seams to get them into the session after about 20 attempts.
We had same problem. After updating to newest version, roblem was solved.
