I cloned the project from Agora/Flutter repository and then I ran the same program on two devices (android emulator and Redmi 7). The problem is because when I type the channel on a device it opens the call (ok) then I type the same text on another device it's like another channel has been created --> they dont't share the channel splitting their screen.
