Screen Recording

I have an Xs Max, 15.4.1, and have recently discovered that I can screen record. However, as soon as I discovered this amazing feature, it stopped working correctly. Lol. When I try to record ZOOM meetings, the volume doesn’t record. When I first started recording the ZOOMs, it worked. But now it has stopped recording the audio. I have made sure the screen recording microphone is on.

I tested the feature on a podcast and it recorded the audio so why did it stop recording the audio when I screen record ZOOMs?
