The divers at the start of the movie use standard scuba regulators and demand valves that sit in the mouth. It is all but impossible to speak to another diver with such a mouthpiece, and unless you have a full face mask, impossible to communicate with a surface vessel.
With full access to the scale mechanism, it would have been simpler and easier to just block or brace the scale to prevent it from moving, rather than freezing it.
500 liters of liquid nitrogen would result in about 350.000 liters of nitrogen gas. This would fill the entire chamber where Simon is and cause asphyxia due to the dilution of the air and thus reduce the oxygen concentration, but it doesn't seem to effect him. Using liquid air instead would have had the same effect, while maintaining the Oxygen concentration.
Simon listens to the World Cup final on his father's cheap transistor radio deep underground during the climax of the heist. Presumably there are access tunnels and vents that a signal at depth might be possible; but, without an UGR system, a simple transistor radio would have real difficulty getting a readable signal at that depth.
The movie is in the year 2010, but when Thom searches for "Bank of Spain" in a search engine, momentarily "Money Heist" is shown.
The Bank Vault was designed in the 1940s, but the walls around the Scale mechanism are found to include Dyneema. This is a composite material with high tensile strength developed in the 1990s. However, this could have been a recent addition to the original design.
Liquid nitrogen is stored in a large Dewar (i.e. thermos bottle), not gas cylinders as shown. However, the cylinders could have been camouflage around Dewar flasks, used to make them less suspicious.
The time-zones for Spain and South Africa are the same. How can Spain watch the world cup during the day while the game is on during the evening in South Africa?
However, the match kicked off at 8:30 pm in South Africa. As it is in the southern hemisphere, the sun sets in South Africa shortly before 6 pm on average. Spain, in the northern hemisphere, has a sunset time in July varying between 9:00-10:00 pm. Thus allowing for the discrepancy of daylight.

They enter the Bank of Spain to find the treasure's location. But then they won't be able to get the treasure itself: it's impossible to steal such a huge and heavy loot from the second bank. However, this movie does not show them doing that, so it is not a goof. An "impossible" heist was the definition of this movie, and a sequel might show how it is done.
Gold is nearly twice as massive (heavy) as lead, yet containers of the "treasure" are moved with little effort.
Thirty-two minutes into the film, the head of security of the Bank of Spain drives up in an Audi A7, which was first released in Fall of 2010. The model he arrives in is the post 2015 update.
During the initial reconnaissance to find access to the Bank of Spain's vault, James and Simon walk down the subway line to a old track which leads to an old workers space. If the Vault is that secretive to its security, surely even these old access tunnels that would lead to it would have some kind of intrusion detection and monitoring rather than leaving an unguarded or multiple unguarded access point(s) to it allowing ease of access undetected.
