gs.addInfoMessage not showing up on (government Service) Portal in Before Insert BR on attachment.

[ParamP]

This is my code - 
As an admin,  while on playbook experience on Portal, I can see the addInfoMessage instantly, when needed. But as a constituent, non SNC Internal role, on portal the mesage does not show up instantly, it shows up when the window is refreshed. Below is my code.

(function executeRule(current, previous /*null when async*/ ) {

    // Add your code here

    var MAX_SIZE = 10490314;

    var mimeTypeArray = [];

    var propertyValue = gs.getProperty('attachment.allowed');

    if (propertyValue) {

        // Split the property value by commas and push it to an array

        mimeTypeArray = propertyValue.split(',').map(function(mimeType) {

            return mimeType.trim(); // Trim spaces around each MIME type

        });

    }

    var val = mimeTypeArray.indexOf(current.getValue('content_type'));

    if (val == -1) {

        gs.addInfoMessage("infoMsg");

        current.setAbortAction(true);

        gs.setRedirect(current);

    }

    if (current.size_bytes > MAX_SIZE) {

        gs.addErrorMessage('File size exceeds the maximum allowed size of 10MB.');

        current.setAbortAction(true);

    }

})(current, previous);

I have also tried removing and adding 'gs.setRedirect(current);' in the if, but it makes no difference.

@ParamP 

so your business rule is running but for snc_external info message is not showing?

If my response helped please mark it correct and close the thread so that it benefits future readers.

[ParamP]

The business rule is running, the attachment uploading is aborted (as I need it to), the alert does not show up instantly, but when I refresh the portal page, it shows up (as a constituent).
As an admin, everything happens, and the alert shows instantly as expected.

 sn_gsm.constituent (related to PSDS module). It's an external user role.
