In the first episode it is established that the hotel is a "dead zone" with no Wi-fi, mobile phone, or Internet connection. However the character of Tristan Duffy is seen on his mobile phone using an app that resembles Tinder.
However, it is possible that Will Drake had signal boosters brought in or a wi-fi network installed sometime before the episode starts, given that he is hosting a fashion show for high-profile guests.

During the fashion show, the Countess (Lady Gaga) is wearing a white outfit, matching the one of her companion's. However, right after the catwalk, when she stops Donovan's fights with Tristan, her dress is black, although her make-up and jewelry haven't changed, nor her partner's costume.
After Mr. Lowe's daughter shoves her phone into his stomach and then he and his wife argue about their son, Mr. Lowe is shown holding the phone in his left hand, reaching for the wall with his left hand. The next shot shows him pressing his left hand to the wall and looking at the phone on his right hand.
Sulfuric acid will react with many metals in concentrated form and it becomes a strong acid in diluted form. Therefore, when Mr. March (Evan Peters) is seen pouring sulfuric acid in a tub of what appears to be zinc, it means that the acid would corrode the tub and risk spilling its contents.
The detective flashes back to a murder scene where the kids have been poisoned by carbon monoxide.
They all have pale faces when in fact carbon monoxide would cause their faces to be bright red.
During the flashback when Iris is telling the history of Mr. March when the detective at the body dump is examining the scrap with JPM on it the supposedly dead body in the background is clearly breathing.
Holden is playing Atari game Space Invaders with a Joystick, but is holding it upside down. The fire button should be at the top. Though he would be able to fire the gun, his up, down, right, left movements would be backwards.
When Will Drake is having his runway party at the Cortez, John Lowe's daughter Scarlett shows up. John never says her name nor does anyone else, yet Will introduces her to his son. He shouldn't know her name as he had never met her or heard her name before that moment.
John Lowe says that March "made a killing in the Depression." But the flashback shows that March had already made his fortune by 1925 when he built the hotel.
