I did, while it mostly okay, I don’t like the mobile notifications limit. Even for a family, ten people is quite small, as inviting a couple of friends would reach the limit.

With all the chat options, I’m looking for a self-hosted fully controlled version. So for me, that’s a bit weird that a self-hosted version is crippled in any way. If Zulip allows me to self-host the mobile notification thingy, then I think it’s a good alternative. I haven’t explored that yet.
