Changing countries allowed to join setting. Error code 1142

[Leonotta]

I inadvertently set my zoom meeting to ONLY allow United States users to join my meeting. I need to be able to disabled whatever I did when I first set it up so that I can choose all countries. My user from Canada attempted to join my meeting. We went over and troubleshooted all the settings and could not get zoom to allow me to change settings to "all countries" instead it is stuck on Unites States only. She received error code 1142. Any help is GREATLY appreciated. We tried everything
