Hey @Vic1100. Could you try preforming this, but with your wifi off and just using mobile data when using the Ring app? This may help save that change! Please also ensure that the shared user doesn’t already show up under the Main Menu > Settings > Users, as that may also be why you are unable to add them. If this persists,please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19. This has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support. Let me know how this goes!
