Camera Preview Unavailable on All Stick-up Cams

Hey Community. I have two Stick-up Cam (3rd Gen) cameras that are consistently showing "Camera Preview Unavailable" in the app, in the browser, and no video when attempting to do a live view. They are connected via solar panel. Things I've tried: 1. Resetting via the bottom near the battery slot 2. Trying a combined 2.4ghz/5ghz network, then switching to a 2.4ghz-exclusive network 3. Letting the cameras die before starting them up again 4. Charging the batteries to full before starting them up again 5. Rebooting the cameras over, and over, and over again Every so often, the devices will show "Installing update" as if a firmware update has gone bad. I'm out of ideas as to what to even do, I've exhausted all options that I myself can think of.
