Does the user have permissions to view the default app

This was tested with the default akadmin user.

I decided to test on another VM and everything works perfectly on 2024.4.2 but after updating to 2026.5.3 I get “Redirect URI Error” on some applications but get login loop on other applications.
Then some apps don’t reach authentik at all they just go to FQDN of the application with 403 access denied

#

Not a single application works anymore
