Ring CX Voicemail triggering a new browser tab and re prompting log in

Have stumbled across one of our users with a unique problem. 

User has access to view an inbox where voicemails are left in Ring CX.

This inbox displays the VM as a separate link the user will then click on to actually hear the VM. 

When the user clicks this link a new browser tab is opened and they are prompted to log in again to Ring CX. This turns into a loop where every time the user goes to access the VM they are just asked to log in again. 

Looking for suggestions on how we can solve this, expected behaviour is that it opens the new tab and just starts playing the VM, it does this for me and our others users.
