Recording and Spotlight Issues with linked battery spotlight cameras

I have an issue that affects my two battery Spotlight cams linked devices at night only and I suspect it’s a firmware issue. When I first purchased my devices in Nov/Dec 2019 I had no issues with having my two devices linked. Since mid Feb 2020 I’m having issues which leads me to think it’s a firmware bug as they are both affected. I have tried playing around with settings, remove and re-setup my devices, improve RSSI. Nothing has fixed my issue. My issue is: I have 2 battery spotlight camera’s linked, both installed at front of house with both devices to trigger recording and lights on if either is motion triggered. Both working ok from purchase November 2019 to start of Feb 2020. Since mid February 2020, the ‘linked device’ has issues with recording and spotlight flashes on for 2 seconds and then turns off but continues to record in black & white (night vision). Can see this clearly happens in night video recordings - records in colour, LED spotlight turns on and 2 seconds later switches spotlight off and continues to record in night vision. Also another issue is that the ‘linked device’, when recording at night, the video appears to be recorded in very low dim light (even though LED spotlights are at full brightness) and so the video appears to have a very shallow and dim appearance, so video recording is next to useless as can’t see any detail in such low light video recording. When either of these cameras record video at night as the first triggered camera - primary device (not the linked device) they record video as normal and LED spotlight remains on for full duration. Can Ring Support please investigate this issue?
