Stick up cam freezes after motion detection

Hi - I've had my battery stick up cams for over a year, and recently they've both started freezing at random.Following a motion detection, they start recording (but video only reflects a couple of seconds of motion). Footage afterwards is marked a "unavailable" but blue light on camera stays on, draining the battery. Device health in app still shows as "Online".I can reset by removing and reinserting the battery, but defeats the purpose of having security cameras if I never know whether they're actually detecting motion or not!Firmware on both cameras is showing as up to date.Any help appreciated
