Ring Doorbell 2 stopped motion detection

I have had my Ring Doorbell 2 installed and working since November 2018. As of yesterday morning, it has stopped recording or alerting me to any motion triggered events. Prior to this, it has worked fine in this regard. I can still access live view, and a recording is generated any time that I do so. I did notice that when I rang my doorbell yesterday, it also did not generate any recorded event or alert. I have tried doing a hard reset. My firmware states it is up to date. I tried altering my motion settings and frequency. I updated the (iOS) app. I have not yet removed the device in the app and reinstalled as new. Nothing about our home WiFi was changed within the last few days. As of today, I still am not getting recorded events or alerts for motion. Has anyone else had a similar problem?
