Speaker view not working when sharing screen

When I screen share, the speaker view  function doesn't work as it used to. The camera only stays on one guest and doesn't switch between speakers. 

When I run a normal zoom meeting the speaker view will switch to whoever is speaking but as soon as I share my screen this function stops working and like I said wont switch between speakers.

When I see the recording I cannot see the person speaking when the screen is being shared. Does anyone know why this is happening and what to do about it?

This is a new issue and is EXTREMELY inconvenient and frustrating as I've done this dozens of times in the past and not have this issues.

Thanks in advance for any help or suggestions
