By default, the app suggests the next User as the User with the fewest number of meetings to date based on the rules you set up.
Flexible Round Robin
If the queue is flexible, the User can "skip" the suggested User (the User with a star by their name) and manually select other users in the queue to book a meeting.
In this example - Nate was suggested, as indicated by the star, as the next Assignee, but other Assignees could be chosen.
This setting is helpful when you want to allow your users to make other selections. This is what the setting looks like in the queue settings:
Strict Round Robin
In the case of a strict round-robin:
The User can't select other users. They can only select the next User in line to receive a meeting. If the prospect wants to book a time that's unavailable for the next User in line, they have the option to select
Availability for all
In this example, Ashley cannot be skipped. Still, the booker can choose "Show availability for all" to show the aggregated availability and blindly pick a time for a different rep.
