Cams working fine. Events captured fine. Playback button inoperable. Legend has it that it worked in the past. New day, new problem.
I assume you have an SD card in your camera, have you checked the card to be sure it is still good.
Playback button is working fine for me.
My guess is either a) you didn’t realize it was to access the as card or b) there is some problem with your cam reading the card.
Double check the card wasn’t removed. And I would reformat it in fat file system (on a computer) That should fix it up
If your still having trouble after that I would contact support.
