pidgin, gadjim, chatty, dino, kaiden, psi, psi+… some other ones
it isn’t automatic from what I have found. vague “omemo”-related errors are popping up here and there.
what set up do you suggest where the experience is simple? it seems that there are a bunch of standards which servers and clients have varying support for. plus there is a plugin architecture for lot of them which extends or changes functionality, or it matters what version of libraries were used in compilation, and many other little details.
I believe that some people do have a seamless experience but ours hasn’t been. If there is some sort of documentation describing exactly how to get going I would appreciate it.
