Screen broadcast share with ReplayKit Not working

I have performed the steps provided under the below link

to create a broadcasting mechanism to share the screen of host, but not able to see anything at participants end.

  • MobileRTCShareServiceDelegate is not getting called
  • onClickShareScreen not implemented this as it was not there in sample app
  • App group is consistent everywhere requested.
  • Have already followed the trouble shooting steps provided in one of the articles.
  • sampleHandler delegates getting called if I run the extension separately.

Host is hosting the call from iPad. Audio connection setup is happening , its just that the screen share is not working.

Please assist ASAP.
