Sea Change - S3-E1

Who Shaves the Barber? - S1-E7
Continuity mistake: When Molly visits Wes Wrench in the hospital we see the whiteboard on the wall has writing on it. Molly takes it off the wall and hands it to him without erasing it and it's suddenly blank.
Revealing mistake: When Iris is sitting in bed recording the message for Barry, she is holding her iPhone so that the start button is on the left side, but the "video record" button appears on the right. Additionally, her right hand covers the speaker area of the phone fully, including the front facing camera. It is impossible for Iris to be recording the video live and reveals that the video footage was recorded ahead of time. The illusion that the video is being recorded by Iris live is further ruined by the fact that the room lighting is turned off in the scene, but the recording is well lit. (00:02:55)
Factual error: On the map behind the colonel during the first scene, Iceland is labelled as being under Nazi control. This is incorrect, as the British were in control of the country during the whole of the war. (00:05:10)
Character mistake: In the 11/14/2005 US Army Rangers report about Peter MacLeish, the word captain right under MacLeish's signature is misspelled "captian."

Right as she says this line, the camera cuts. In the first shot, she has one pencil in each hand, but in the second shot, suddenly both pencils are in her left hand. The position of her hands changes between cuts as well.
Visible crew/equipment: A camera and microphone are visible on the front of Walt's vehicle after the opening credit/intro as he takes Ruby's call, explaining he's headed to Denver. (00:01:35)

Chapter One: Suzie, Do You Copy? - S3-E1

A Day in the Life of Retsuko - S1-E1
Continuity mistake: After Ton bashes Retsuko for not getting her tea right, she sings some death metal in the bathroom before joining Fenneko back at the computers and they start talking. Between them is a pink cup with some orange scissors, and an assortment of writing utensils. They are fanned out, but show that the red one is closed to Retsuko with the black in the middle and the yellow closer to Fenneko. When the camera changes angles to show them both sitting there, this order of pens is flipped, with the scissors still being in the same spot.
