Video Doorbell Pro - motion alert notifications stopped but ring alerts still working

My Video Doorbell Pro has suddenly stopped sending notifications for motion alerts, but still notifies for ring alerts. This began on May 28th just before noon EDT and with no manual changes on my part to the doorbell's settings or my Android phone's settings. I have tried everything listed in [How to Troubleshoot Ring Notification Issues for Android Devices](https://support.ring.com/hc/en-us/articles/211676423-How-to-Troubleshoot-Ring-Notification-Issues-for-Android-Devices) including reinstalling the Ring app, toggling notification buttons in the system app setting, rebooting the doorbell, and restarting my phone. What else can I try? Are there known issues? Video Doorbell Pro Voltage: Good (18V) Signal: RSSI - 40 Firmware up-to-date Phone: Google PIxel 4a 5G (up-to-date software) Ring App: 3.60.0
