Spotlight Cam - Black Screen Video Recordings

I have a strange issue. I have a Ring doorbell and a Ring Spotlight Cam. Both work fine on live view. The doorbell displays video recordings perfectly but all the videos captured on the Spotlight Cam are black when I try to replay them. I’ve deleted and reinstalled the app but not sure what to do to fix the video issue. Everything online says it’s a router issue but the doorbell works fine and live view works fine. This only started on the 1st June.
