The broadcasts.churchofjesuschrist.org URL does not seem to be functional. However, using the URL
https://www.churchofjesuschrist.org/media/broadcasts will get you to where you need to be. Published events from meet.churchofjesuschrist.org will appear on that page under 'Local Broadcasts" if you are signed in with your church account. You can also enter the event code on that page to access the broadcast. If you are not signed in or do not have an account entering the event code will still take you to the broadcast page. This method of access does not require the guest to open or use the Zoom client on their device/computer.
This is my first time using
Meet and
Broadcasts for a Stake Conference General Session. I didn't create the event in Meet, I scheduled and set it up in Zoom as normal. The event showed up on the Meet page and just needed to be Published to appear on the Broadcasts page. It will be interesting to see how it works out. Hopefully they can get the broadcasts URL to redirect soon
