It can't be fixed. It's dead. Matrix is the modern replacement.
I used XMPP to implement a chat client within our application around 2012. It was a freaking nightmare. The roster system, the incompatibilities, the lack of standardized synchronization, the never-working group messaging.
Lots of good XMPP implementations disprove this.
I hope Matrix just goes away and stops distracting the FOSS community from improving existing internet standards instead of custom protocols by random startups :)
A list, please. For iOS, Android, macOS, Windows.

XMPP had its chance, it blew it.
It's not like Matrix is killing it.
It's not exactly a new protocol, yet still feels like it's in the pre-alpha stage. Both protocol and the client/server software.
