Before you go live:
Double-check that you have a strong connection and full battery, and advise your guest to do the same.
Avoid using external microphones.
Test out going live so you're familiar with the interface and where to locate the LiveWith button.
Make sure you know your guest's handle to make it easier for you to send/accept a request.
During your live:
Have your guest request to go live with you, making it easier for you to add them to your broadcast.
You can also host a product launch while going LiveWith your co-host.
Only the host of the live can tag products in the stream.
