Very poor video quality after camera update

My Ring security alarm system and cameras updated about one week ago after I had to reboot everything due to connectivity issues; ever since then my indoor cameras have extremely poor picture quality and recordings are the same; there’s serious noise and light levels flash up and down on screen. This affects my home security as video footage is useless and could not be used to identify anybody, not even my family it’s that poor. Nothing has changed at home other than my devices being rebooted and updating. My download speed is 33.mbps and upload is 8.8mbps according to the speed test accessible via the Ring App. Anybody else having this issue or have a fix please?
