Only for mobile, no? Element X for desktop is still in development, last time I checked, and the old client is as bad as ever.
Element is the only piece of software where logging in and out (I don't want to be permanently logged in) proved to be too much of a challenge - I was regularly losing encryption keys on different devices.
If you are ever at a point where you have no active sessions (aka “devices”) then other clients will not be able to send you the keys to decrypt their messages.
This is one of the many ways to get “unable to decrypt” errors in Matrix.
