Ios or android? I have had great success with conversations on android
I'm now actively trying to get contacts off XMPP because XMPP is too unreliable for me.
And that's before we talk about the sad state of XMPP apps on the desktop. You cannot win the messaging market when you have only one good app on a single OS.
I mean I get it, but those who trade security for convinence deserve neither
If you only need to support one platform maybe it's doable, otherwise just not worth it.
