I was able to finally get sliding sync up and running with my dendrite server!

Element X and Schildichat next allow me to sign in with no "this server does not support sliding sync" error.

However these clients do not show my chats or rooms. If I try to create a room it will work but if I bavk out it will show a blank chat page.

If I go to the regular element client I can see the newly created chats from element x/schildi.

Any help would be appreciated!

Edit: sliding sync now works it was an error in my compose file for the url! I needed it to be set to my matrix url and not my sliding sync url.
