Good question @Bumpydog! As long as you remain subscribed, your recordings will be available for 60 days. If there is any lapse in subscription, such as trial period ending and subscribing afterwards, those videos would not be saved. If you feel you subscribed on time and while the trial was still active, try removing and reinstalling the Ring app on your mobile device.
Our support team is available to look into this further for you, if the above does not resolve your concerns.
