What makes you think that? I haven't experienced, or heard of people having frequent crashes. Me and my family also use it to communicate to each other with no issues regarding the UI.

As a counterpoint, I use conversations literally every day, and cannot recall the last time it crashed. My partner and kids have used it for at least the last 7 or 8 years to communicate with me and each other. I don't claim there are no issues, but "crashes often" isn't something I would expect to hear about it.

I don't find the UX to be clunky either, but I acknowledge that could just be my familiarity with the program, so I would leave that for others to dispute.

Crashes?!? I've been using Conversations for a long time and can't remember any crashes. Something must be wrong with your setup.

For me, the bigger problem is that I was unable to get OMEMO + Apple Clients working properly. I think OMEMO 1 has some design flaws and hope that OMEMO 2 will fix those.

I ran into this exact problem. I needed to fork Conversations to add a lot of polish. My fork is definitely improved but still has a few rough edges I'm chipping away at.

Conversations doesn't crash at all for me.

And I moved to Conversations because I needed a client that wasn't as crashy as Xabber was for me.

Seriously? I'm not saying it's the best app around but the family uses Conversations and we never really have any real issues. Even for the septuagenarians in the family I just set it up once like 7 years ago and they still use it all the same.
