Element X funktioniert nicht

Matrix-based, Element X lets you self-host your data or choose from any free public server (the default is matrix. org, but there are plenty of others to choose from).  All the power of Matrix - and the complexity of decentralized end-to-end encryption - is now hidden under a beautiful and intuitive user interface using the very latest frameworks and accessibility features.  Element X delivers speed, usability and reliability on the decentralized Matrix open standard.  It’s not just the fastest Matrix client, it’s also fresher and more reliable.  It’s so fast for a number of reasons, but in particular we’ve introduced a completely new synching service (‘sliding sync’).  It’s fresher because we’ve rebuilt the entire user experience.  Enjoy the freedom of the Matrix open standard!  Enjoy your right to private conversations - free from data mining, ads and all the rest of it - and stay secure.  So just like email, it doesn't matter if your friends are on a different Matrix-based app you can still connect and chat.  It is the brand new, and fastest ever, Matrix client.  However you host, you have ownership; it’s your data.  So even in big end-to-end encrypted chat rooms it operates incredibly quickly.  A complete new build, Element X transforms performance.  It is for personal and community use, and will support enterprise functionality later this year.  You have native interoperability with any other Matrix-based app.  You’re not the product. You’re in control.
