Problem with iphone and web appli on the same room

Hello,

i have problems to have users with the web application and users who are with the smartphone appli on the same room.

I have only the people with the web appli on my room if i use the web appli, and not the people on the smartphone appli, and if i use the smartphone appli i can have the people on the smartphone appli and not the people on the web appli.

Is there a way too have both on the same room ?

Thank you

Thierry
