[catherd]

When we did our testing we went through all the iOS settings and more than one user was testing on iOS. It was a client problem, not a settings problem.

Everything here sounds to me like "with a year or two of improvements, non-technical users might not run away screaming". I would love to use a federated chat protocol, but the reality is that XMPP isn't in the same league as other chat programs right now from a feature perspective, ease of installation, client availability, or user friendliness standpoint.

My company tried it, hard, for about 3 weeks. I paid something like $2000 in consultant and employee time to do that test. I was willing to deal with it because it was literally the only option in our case (we needed to avoid google push notifications). Once we realized we could make Zulip work by routing push notifications through a separate service we switched and almost everything about Zulip works smoother and with more useful features. None of these replies are convincing me that XMPP would work any better if I just knew more about how to install it right, etc. Again, I would love to use an open, federated chat protocol, but XMPP isn't useful right now in the ways I need it to be.
