Floodlight CAM shows both offline and online

Sometime between the 6th and 7th of July, all four of my Floodlight CAMS went offline and could not talk to the Ring servers. My Ring Doorbell Pro continued to function normally. Nothing at my end changed and WiFi signal levels were still very good (each CAM's "Device Health" button still worked and showed the device as offline but good WiFi signal level). Over the next few days, one-by-one, each Floodlight would start reconnecting to the Ring Servers except for one which shows itself as not connected in the thumbnail view of all cameras in the Windows Ring App, even though it successfully updates its view every minute; however, if I go to "Device Health" for that Floodlight, it shows it as online and good WiFi signal strength. This Floodlight even occasionally sends some motion-detected video up to the Ring Servers. Power cycling the CAM didn't change anything. Anyone seen this before and have a solution?
