I’m so sorry you guys are having difficulties. I’m on version 202402141744. I have users on Ubuntu, Android, and Debian. None are having difficulties. All Linux users are using either a .deb download, or the repository install. The Androids are mostly off the Fdroid install, and I think one may be off the Google Android store. I regularly have video conversations which run faultlessly for over an hour at a time, and all messages and attachments arrive almost instantly.
In my opinion, Jami is now a mature system.
