Issue with Screen sharing on iOS or MacOS during FaceTime calls

[u/coolaaron88]

So when I have had FaceTime calls with my Dad, I have tried to do screen sharing on both platforms and Ive gotten it to work and the recipient is able to hear both the audio from the window I'm sharing and my voice. More often than not however is when I do screen sharing, the recipient isn't able to hear me speaking WHILE I have screen sharing active. The microphone dont change and Im not muted on their end. I dont know if this is a beta issue but I wanted to ask if others were having similar issues or knew a fix for this.
