Test ends without interactive confirmation

I am using iPad Pro and iOS version is 18.4.1.        Zoom version is 6.4.5(24064) 

When I test my setup by accessing to zoom.us, test for microphone, speaker and camera runs without any interactive confirmation for each then ends.  Only green check box is shown for each but without confirmation .    I once deleted zoom application and reinstalled but not resolved.

I have a Windows PC and Mac Mini too but test goes with interactive confirmation as expected.  

I appreciate any suggestion to resolve.
