Lorenzo Setale reviewedRiot.imA universal secure chat app entirely under your control.
 RecommendedPros: 

Easy to link between multiple communities/systems (ex: Slack, Discord etc etc), it has the right features for teams and private rooms

Cons: 

Encryption is a little frustrating, but new updates are coming

I have been using Riot on Matrix for over a year with the team and it was never a problem. The app is getting better and safer and better and that is way more important than emoji updates

Lorenzo Setale has used this product for one year.
