Error - requires participants who attempt to join my zoom room to be "authenticated" despite setting

[gershon2]

I created a zoom room with the setting for requiring authentication is NOT being enabled and NOT required.

My participants have been getting an error saying that it is required.   My meetings DO NOT have authentication required - but meeting participants keep getting an error message saying that it IS.

Please advise on how I can fix this. Zoom was not usable and had to meet with another software.
