When Ronny plays the tape he got from the O.N.E. camera, the way Parker says his lines is different from the way he said them in the actual scene with Mrs. Davis. The words are all the same, but the delivery of them is different in both scenes.
When Willie is rubbing lotion on his arms when he and Thorold are on the VR beach, Thorold takes his goggles off with hand, then puts them back with one hand. When he is shown back in the VR, he is shown using both hands to put his goggles back on.
Just before Thorold and Willie appear in Helen's hideout, Jake is watching one of the videos from Helen's grandmother. Somehow the TV turns itself off because no one has a remote. This is evident because Jake has the VR goggles, not a TV remote.
