Can't disable login screen for anonymous user

The Issue

I have enabled anonymous access on my Artifactory Cloud instance and set the appropriate permissions for the anonymous user to be able to read all repositories. Requesting artifacts from a build tool such as Gradle or Maven works fine. However:

• Navigating to the web UI immediately takes me to a login screen despite having disabled it in the settings.
• After clicking the X button in the top right corner of the login screen, the screen only disappears for a short while and then comes back.

Workaround

To temporarily work around this, refresh the page and then click the X button to exit. The logon page won't come back this time.

Expected behavior

Anonymous users are not shown a login page when they open the web UI.
