OMEMO doesn't work in MUC with the iOS client

[Hund]

My partner and my sister are both using Snikket on iOS. A platform that one might have a lot of options about to begin with. When my sister activates OMEMO, my partner can't see my sisters messages. Everyone can see my partners messages with OMEMO enabled though, including my sister.

I have looked around in the client for iOS, but it doesn't seem like there's any settings for anything.

What's wrong? And is there's something they can do? Other than throwing away their shit phones. :D

Ops. Wrong repo.
