Kizuna adding contacts

Hi all

I have Kizuna installed on 2 devices with my household. I have registered two nicknames and I can chat between accounts. I have setup another Kizuna in a different location (not home) but when searching contacts to add, I cannot find the two accounts I made. In fact, I cannot find any other users at all.

I am using the latest Holochain Laucher and latest Kizuna.

Any ideas?
