The desktop app takes several minutes to open (at least on Linux), so I find that the only way to use it is to start it at boot and always leave it open. I'm still hoping that someone may create other clients, e.g. a Pidgin backend.
The mobile apps, on the other hand, work really well. Been using them for years now, both on Android and iOS.
I also see that the other issues I noticed previously (high latency when typing, “compose key” not working) have now been fixed as well.
