I am having issue this quite frequently. I would be on zoom meetings on my phone on the main speaker for volume. When I receive a regular Phone call or even a missed call during the zoom call, if I answer or disconnect the call, and connect back to the zoom meeting, the volume from main speaker switches automatically to the small speaker on top of the phone and its barely audible. I have tried to turn off Bluetooth when this happens which resolves the issue temporarily but if the Bluetooth is off it does not switch back to main speaker at all unless I log off of zoom and re login again.

Clearing the app cache is kind of like a cleanse for your apps. It will get rid of residual files that could be slowing down the app. Open Settings, and then swipe to and tap Apps. Select or search for the app you want to clear. Tap Storage, and then tap Clear cache.
If the issue still persists, kindly register your concern in the Samsung Members app (Samsung Members app > Get help > Feedback > Error report).
