As has been widely reported in the last week or two, the latest update to the Logi 2 cameras doesn’t seem to play well with HKSV recording for many people.
I also had this problem and tried to re-associate the cameras, with no value.
But today, by chance, I think maybe I made a discovery.
We’ve updated Apple TV to the latest beta version of tvOS. I thought “what the hell” and disconnected the cameras and then connected them.
And BAM, everything works so far.
So try upgrading your Apple TV as a hub to the latest beta!
Let me know if this works for you or if you read and figure out why you are likely to suggest Apple or Logitech …
