Almost feels like they bit off more than they could chew with some features. The end to end encryption of group chats is pretty revolutionary, but it's never really felt like it worked, and none of the competitors even try as far as I know. It's just too hard. Being federated probably makes every feature 10x harder to implement.

The bridging feature that they sell also never really worked properly for me. It would go down almost weekly, messages would go missing, get delayed, get reordered, etc. I never felt confident using it and would have to check the actual app to see it come through as expected.
