Ring Alarm offline for Shared User only

Hello All,I just installed a Ring Alarm today and as the owner I have access from my Android phone and can use all of the features of the Alarm.However, when I add a shared user who currently has access to a Ring Floodlight and Ring Stickup Camera then the Alarm does not appear in their dashboard on their Android phone. When I look at Devices from the menu their "Alarm Base Station" appears as "Offline" whereas it appears as "Online" for me and I can confirm it is working.Any ideas why this is?PS. Their PIN code can disarm the alarm from the keypad OK.Thanks.
