Friend Safari bug...?

(hopefully i’m posting in the right category) I’m not too sure if this is just a problem on my side but my friend has been saying its been happening to him too. The friend safari will only have 1 Pokemon appear in it, and nothing else. Was this intentional, or is it a bug? I’d like to shiny hunt for Eevee but i can’t since only one Pokemon appears in this persons safari (and others that I have tried)

Do I have to beat a certain number of gyms to get more Pokemon?

Yeah, iirc it was gym 6 for slot 2 and Elite 4 for the third one, may be wrong on the exact points but you need to progress much further to unlock the slots now.

These are the conditions from 1.2, yes.

Thank you!
