@aral if you want an encrypted matrix client that’s almost sure to work, you could use https://matrix.org/docs/projects/client/hydrogen; it’s optimized to runbon anything over having a wholly complete feature set.
i’m uncertain that matrix has the same metadata privacy controls as signal does, but they are also working on a p2p solution that runs a local Dendron server; https://matrix.org/blog/2020/06/02/introducing-p-2-p-matrix/
though i’m sure you’ve heard of all of this 🤷
@calebjasik Yeah, Matrix is just too complicated for me to get my simple little head around, sadly.
