Custom Self Service branding no longer applies to icon in notifications

Has anyone else noticed that custom Self Service branding no longer applies to App Installer / Notification Center notifications?

Environment:

• Jamf Pro (current version)
• Self Service 11.28.1
• macOS Tahoe 26.5.1

What I’m seeing:

• Self Service branding is configured correctly in Jamf Pro.
• The custom icon appears correctly in the Self Service UI and as the application icon.
• However, macOS Notification Center notifications (e.g. App Installer update notifications) show the generic Jamf icon instead of our branded icon.

Some investigation:

• Notifications appear under Management Action in System Settings > Notifications.
• CFBundleIconFile for Self Service points to AppIcon.
• AppIcon.icns appears to contain the generic Jamf icon.
• Running selfservice branding brand --icon <path> changes the Dock/Finder icon but does not affect notification icons.
• The behavior appears to be specific to notifications delivered via Management Action, which is how they appear in System Settings > Notifications.

I found a few older discussions from admins reporting the same behaviour and suggesting it might be a bug/regression.

Questions:

1. Is this expected behaviour in recent Self Service versions?
2. Is there currently any supported way to brand the icon used for App Installer / Management Action notifications?
3. If this was a bug, has it been fixed in a newer version?

Thanks!
