Please confirm your Protect Plan subscription status if your video recordings are not showing in your event history, or showing an error when trying to play. This can be done by logging in at Ring.com via web browser and clicking the Protect Plans option on your Dashboard.
Playing your recordings from the event history via web browser is also a great test to see if your recordings work there. If you are needing to subscribe to a Protect Plan, visit our Community article for steps on subscribing. If this concern persists, our support team is always happy to help further! 
Please give our support team a call at one of the numbers available here. If you are outside of the US, please visit here to see how to contact support.
