Recently I have made video call with my friend, she can see me in video call but I cannot see her. We both open camera but still, only me who cannot see anything. We tried to change front camera or back camera but it's still cannot see. The only thing I see is a black screen when she open camera. I checked in my app management info to allow permission to everything but I still cannot fix the issues. Please check this issues and provides me some solutions please! Thank you
