Singers can't log on

I’ve just done my first test of Flock with my husband and daughter in our house before doing a larger test next week with my choir. We’re all on the same wired network, all using Mac. They could both separately access the choir screen for a couple of seconds, but then would be kicked back to the sign on screen. I could see them accessing the choir screen, but they couldn’t see the other one there.
I’m guessing that it might be to do with them using the same network as me?

Great to hear that you’ve started testing with Flock and welcome to the forum!

Exactly right… the Leader and Singers need to be on different networks.
Two singers can be on the same network, but the Leader needs to be separate.
