unable to join meeting "The meeting is scheduled for" wrong date and time thank scheduled.

several users in our organization have experienced an intermittent inability to join scheduled RingCentral meetings. They are presented with a message that says "The meeting is scheduled for (date/time)" and cannot proceed any further (screen shot attached). The date and time in the error message is random and does not match up with the date and time of the meeting the attendee is trying to join.
