Hi Michael, I have faced the same issue on some training/ meetings - here is what I did which worked quite well (I lost a few persons in the process, but probably he was not really committed to participate fully)
My idea was it was easier to deal with before than during the training.
So here is my two cents :
Before the meeting:
? Have a confirmation to be sent by attendes who have done the prework 2 days before the meeting (or a questionnaire about prework to be answered ) and send back the link / password to the meeting after the confirmation / quiz is received (and make clear it¡¯s the only way to get access)
? if nothing is received one day before the meeting- reach out to check in and give a reminder on the rule.
Good luck :-)
