In Business Hangouts, you can have up to 10 presenters at the same time, however, in order to prevent too much confusion, we really do recommend that no more than one or two people share their screen at the same time - with only one person screen sharing being highly recommended.
This prevents your audience from getting too lost in the content - especially for those joining on small screen devices like mobile phones or tablets.
It is for this reason we recommend only one person share their screen at a time.
As always, let us know if you have any questions, comments, or suggestions by sending us an email to firstname.lastname@example.org or clicking on the 'Submit a Request' button along the top.
Thank you for choosing Business Hangouts!
