Visible crew/equipment: When the "pizza delivery guy" rings the doorbell Bex gets up, and just as Andi gets up we can see the bulging outline of the hidden bodypack transmitter and its wire on Andi's back. (00:22:45)
Visible crew/equipment: At the start, while Bex and Ham are talking about Andi's real father, Andi comes downstairs to ask if she can have the disco ball, and in the overhead closeup of the ball we can see the reflection of the automated camera as it turns its lens toward the mirrored ball.

Continuity mistake: When Andi tells Buffy and Cyrus about the one date with Walker, she gives Cyrus the clear cup with a red design and Buffy gets the green cup, but when Buffy insists that she's the sassy friend those two cups switch between shots, then the cups switch back again. (00:13:50)
Revealing mistake: When Andi walks into the library (this is not Andi's dream) it cuts to the librarian sitting at her desk and we can see the shot is flipped - note the bookcase and the librarian's buttons. (00:10:40)
