No Video found intermittently

I have a Ring 2nd Video Door bell. Intermittently I’m getting a message of a notification ‘Motion detected ’ but then ‘No Video Found.’ The VPN is not enabled. The Wi-Fi is strong. I’ve checked Ring.com and it’s not there. My plan is still on trial as it’s new but I have put in place to join the plan when the trial is over. I’ve checked the history and event history and it’s not there. I can see a lot of people have had this problem. Did it ever get resolved? Thank you.
