@al786 I am seeing the same issue. We just upgraded from 10.4.1 to 10.8. What version of JPS are you running?

10.8 .. Glad to know it's not just me. I tried all the "Tricks" like Adding it to self service and editing the .APP but I know it should show SOMETHING without me doing anything.

We're getting the same here - also on 10.8 - thought I was going crazy!

@al786 do you have a PI number for this?

Whats that? Is this still an issue?

@ginakung PI-006543

This is also occurring on our server which is at 10.9

Throwing our hat in the ring for this one too. How does one lookup a PI? We are running 10.9

Was there a solution for this issue? Running 10.14. Thanks.

It looks like it got broken again - I'm using JPS 10.35.0 in the cloud and I've noticed it for a few weeks now, during some DEP testing with Big Sur and Monterey. I've checked if there is a missing icon in the "Management Action.app", but it's there, so...not sure what's the fix for this. Definitely it's related to the new deployments, since my working Mac doesn't have that issue. I'm going to try to open a case with Jamf, but...my hopes are low these days! :(

I see this same issue and on 10.35 also. 
All my Management Notification popups have no icon and end-users are becoming suspicious of the unfamiliar popup 

Did anyone ever find a solution for this? I'm getting Jamf default app icon or the prohibitory symbol.
