Although Mae is well versed in digital technology, at 40:06 she takes a photograph of her screen with a mobile phone, when a screenshot would have been just as quick and delivered better resolution.

While Mercer is pursued by the drone, a camera is mounted on both the driver's and passenger's windows; however, in one shot on the bridge the driver's side window is wound down.

While Congresswoman Santos is addressing the audience on stage, the lighting on her face varies noticeably between shots.

Inset views during video calls are never displayed mirrored, whilst in real life they are mirrored to assist the user.

(At around 1 hr 15 mins) Just before Mae ended her conversation with her parents on her mobile phone, the background behind her isn't shaking when it should.
