Hi Eric
Welcome to post in the community.
From your description, we'd like to collect the screenshot about phenomenon on your side. As far as I know, generally, you would automatically see other participants video after you join the meeting and needn't to do any settings, The screenshot is useful to understand your situation, it could be involved in your privacy, we'll collect it in Private Message. We're glad to check if there is any workaround on our side.
Looking forward to your update.
Regards,
Joey
