I am hosting a meeting from Taiwan and my customer was unable to join. They received the following error message: 'Unable to join the meeting due to restrictions set by the host's account, error code 13215.' Can anyone clarify what specific restrictions might be causing this issue? How can I resolve it?

I would like to develop a chat room where users can chat, when they agree to have a meeting together at one specific time then the system will schedules and issues and posts a Zoom URL for them to join the meeting. Here are my questions:
1. Is this possible? (I mean this part " the system will schedules and issues and posts a Zoom URL for them to join the meeting")
2. If it is possible, what kind of Zoom account plan do I need to prepare? I assume it needs to issue more than 10 URLs simultaneously.
3. Could you tell me if there is a specific Zoom API that the system should call when issuing these URLs? 

We are having an issue where none of our Zoom meeting recordings are syncing to our CRM, HubSpot, anymore. On 3/28/24, our Zoom recordings stopped syncing to HubSpot. After speaking with support, they said we needed to turn on the Zoom Email Authentication setting, but we've never had this setting turned on before (because this would provide a poor user experience), so that can't be why the recordings stopped syncing.

Additionally, we started using the Zoom Workspace Google integration on 3/15, which we've tested and confirmed allows us to circumvent the authentication settings. However, this now competes with the ChiliPiper Zoom link that's created through our ChiliPiper scheduler (this is pictured below in a test meeting I created. The top link is through Zoom Workspace, and the bottom link is through ChiliPiper).

In this test meeting, the recording did sync when the meeting was held through the Zoom Workspace link (top link), but not when it was held through the ChiliPiper link.

We deactivated and uninstalled the Zoom Workspace integration, but this did not fix the issue of the ChiliPiper meeting recordings not syncing.

Has anyone else experienced this issue? Is there a way to use Zoom Google Workspace <> ChiliPiper <> HubSpot and have meeting recordings synced automatically without the authentication setting turned on?

After creating a meeting invite in Google calendar to include a Zoom meeting, I save/send the meeting notice. Then I access the meeting within Zoom to add an alternative host. When I select save, a new meeting invite pops up (which looks like an Outlook invite) and says that the meeting notice has not yet been sent. The meeting already appears on the google calendar, however, are the changes to the alternate host saved if I do not accept the other invite from Outlook? I have been accepting it, but then I have two meeting invites on my calendar. Is there a way to resolve the duplicate invites but confirm that the alternate host in is place?
