Mimo Call n-1 problem

Hi guys,
I searched a lot in other topics for this problema, but dont really found the same issue.
i’m trying to enter the show 2/3 guests using mimocall, in particular i’m testing it with the Mimo Reporter App.
I can hear all the guests but they dont hear anything from audio return, so guest1 can’t hear me and guest 2, and so on.
I followed all the steps for setting up the mimo call and i think everything is ok, but maybe i’m doing something wrong.
Any help please?

I’m on MimoLive 5.5 and Mimoreporter is 2.2
Thanks a lot
