I did the same...and with time they forced me to go back to Session.

Notifications don't work (good luck with the "Always On" setting and your battery life), making/receiving calls is still useless on slow connections. I've also received so many complains about the granularity of the settings (which is generally OK for control, but the normal user want simplicity).

My only grudge is on the decentralization part. I think Session is way superior in that sense because you don't need to specify the servers, so it's all automatic. As a matter of fact, SimpleX is currently blocked in Cuba because of that — and the build your own sever path is really not an option for mainstream adoption.
