I think that is the answer, I don’t have a WCO and never used one. I think that the change to the new platform pushed the WCO users from 12s CLOUD clips to Thumbnail CLOUD images on the Alerts tab and all along they have been under the incorrect assumption that those were stored on the SD.
No wonder there is no Playback option. It never existed.
Thank you @Newshound, @towelkingdom, @Rareapple3, and @Seapup (for tagging into the ring with the poster I referred to) for the valuable education.
