An essay explaining why we don't plan to use MLS: https://www.poberezkin.com/posts/2025-08-12-mls-the-naked-king-of-end-to-end-encryption.html
A sidenote, is that Nostr's Whitenoise avoids its main problem.
TL;DR: MLS security model is "Trust me bro".
You've established yourself as the secure chat. No refute there.
But you're not usable.
-Notifications are shit.
-No cross device support.
-A sea of technical settings.
-Backups are a disaster.
-Delivery is iffy.
Put the SIMPLE back in SimpleX, and make it as easy to use as Session.
Pre-set all settings, clean the UX, make notifs work, add multi-device support, make backups easy and use a seed phrase to unlock them. Then you will be my go to. Till then, it's Session for me.
Honestly they should make it where if only one device can carry the chat database, then a desktop or server should be the primary device and then a phone or other devices can link to it. Their current solution of linking a mobile to a desktop doesn't really work (at least on iOS) because mobile devices have issues running background processes.
I've never tried Session, and I don't know many people who use SimpleX. I do like SimpleX's idea of no accounts though (Session has accounts).
