sounds very much like a bug.
You can control the Broadcast pop-ups through configuration which should control how the link operates, have you tried setting this to "On Console Open" and see if the link is still present?
I would think that the link is not shown if you choose to have them pop-up.
I had tried that via preferences on the REc (Request Entry console), but just for good measure just tried the same via Application Administration Console->Custom configuration->Service Request Management->Request Entry Management->Default Console Preference->Broadcast Defaults->Broadcast Auto Popup*
It makes no difference.
As a side note. Yesterday after I had set the broadcast Status*='Offline' and the REc preference to "On Console Open" I got the pop-up window when opening my REc even though nothing was listed in the pop-up. Today, presumably since the only broadcast has passed its 'Broadcast End Date+' I don't even get the pop-up appearing. Seems like the logic behind whether to show the pop-up is based on the wrong criteria.
Worth leaving this thread here in case this happens to anyone else.
It's not a bug.
Someone turned off the cart option while I was taking my screen grabs. Presumably the Approvals icon visibility is also driven by some logic.
