double-check the waiting room to be sure that Sembly is admitted and recorded
if the meeting is ongoing, you can reinvite the agent using the +New Meeting button in the upper right

If you created the event in your calendar, but the meeting doesnât appear in Sembly,
for calendar integrations:
enable your calendar integration to invite Sembly automatically in Calendar settings;
double-check if the calendar is connected in Settings -> My Calendars. Sometimes calendars may randomly disconnect for various reasons; read here why;
If you connected a calendar under an email other than the one registered in Sembly, make sure itâs listed in the alias in My Profile settings;
sometimes, calendars can take more time than usual to synchronize changes in Sembly (especially with Outlook). To force this process, you can make another change in your calendar;
If you decide to reschedule your meeting to another day and time when the previously scheduled start time had already begun, new changes won't reflect in Sembly as it has already joined this meeting. Sembly will wait in the lobby for 10 minutes, then drop off and raise the error. You might want to duplicate the meeting in the connected calendar or schedule a new meeting or invite the agent using an instant invite.
for e-mail invites (your calendar isn't connected to your Sembly account):
make sure [email protected] was invited as a meeting participant;
the invite sent to [email protected] should come from exactly the same e-mail registered in your Sembly account, including accurate capitalization (e.g., "[email protected]" vs "[email protected]");
make sure you actually sent an invite (the agent is an attendee for the e-mail invite; invitation mode is correct);
refresh a page, and check again. If the meeting slot still doesnât appear, check the invite details are correct;
double-check your invite date and time - Sembly will attend based on the time of the invite. If a meeting is rescheduled, ensure that an invitation to [email protected] is re-sent.
