The meeting ID is invalid

[Korearobot]

A ZOOM link was created and distributed to other users to proceed with the meeting.
However, among those who received the link, they were unable to attend the meeting with a notice saying, "The meeting ID is invalid."
If you delivered the meeting link to 10 people, about 6 people cannot enter.

After experimenting with many things
1. People who can't come in have nothing in common. (Equipment.Software, etc.)
2. 3001 error number received.
3. You can enter the address ID and PW directly.

We are a company with a lot of meetings. I have to deliver the link address to many people and proceed with the meeting, but it has become difficult.
