Ok nevermind. I solved it. Here’s the steps I’ve taken.
1 - Added google as a secondary login method.
2 - Added a test “app” to the app launcher.
3 - Opened the app launcher and there was a message that I should login and the methods for login was working.
4 - Then I went to [xxx].cloudflareaccess.com/warp, it launched the desktop app.
Now it works.
Going to log out and test on the other devices. If it’s still not working on other devices, I’ll update you.
