**Summary**  
In the login phase, I get redirected to the SSO browser page, I successfully login, the “Launch desktop app” button appears, but the app is stuck in the “Redirecting to browser…/Authenticating in the browser, awaiting valid token” screen

**Steps to reproduce**  
System: Ubuntu 24.04.2 LTS. App: 5.12.0, installed via App Center

**Expected behavior**  
After login I expect the desktop app to open my personal space after clicking “Launch desktop app”.

**Observed behavior**  
The app is stuck in the “Redirecting to browser…/Authenticating in the browser, awaiting valid token” screen. The browser version works fine. I have had no issues before the latest update (22/5/25).

What version is the server? SSO is a feature of a paid license, so you or the admin(s) of the instance can open a support case.

from server info:  
Mattermost Version: 9.11.16  
Database Schema Version: 135  
do you suggest opening a ticket with the server admin? It seems more like an issue related to the latest update

9.11 is an ESR (Extended Support Release) and only provides bug & security fixes. No new features or breaking changes. 5.12 doesn’t support 9.11… you should go back to 5.11 until the server goes to 10.5.x (the latest ESR) [Desktop Releases - Mattermost documentation](https://docs.mattermost.com/about/mattermost-desktop-releases.html)
