Trying to download footage from today but they download as black images,0 minutes and 0 seconds. Yesterday I had no issues. 

I am able to watch them back in playback and can download snapshots (pictures) in live view without issue. I cannot click the record button in live view and download the view. I get an error saying this video is damaged.  

I have tried on three devices, a Google pixel pro 6, Google pixel 4 and Samsung S9 tablet. Its the same issues on all 3.
