I too have issues with the quality of their matrix server. For example server errors out if you try to change a room's notification settings (and the request fails).
I wrote to Purism about that more than a month ago. They are running an old version of Synapse that needs to be restarted periodically so as not to exhibit this bug. Evidently they still have not updated, and they have not even arranged to restart it periodically.
They said Element is asking too much money for consulting on how to keep your Synapse server up, and have no one on staff equipped to do it. So, whatever the status of Librem 5 the phone, LibremOne the service is not a priority.
