Deliberate mistake: If the files on the hard drive are encrypted, as stated, they would also be locked against being deleted by a command, and Atlee would not be able to use a phone in close proximity to issue the delete command. He would need a massively powerful magnet or EMP to clear the drive.
Mission: Impossible - Rogue Nation (2015)
1 deliberate mistake - chronological order
Directed by: Christopher McQuarrie
Starring: Tom Cruise, Simon Pegg, Jeremy Renner, Rebecca Ferguson
Continuity mistake: After reviving Ethan after escaping from the water tank, IIsa's bra strap is visible under her tank top. When she changes later, the bra disappears. (01:10:00)
Ethan Hunt: The Syndicate is real. A rogue nation, trained to do what we do.
Benji Dunn: An anti-IMF.
Trivia: When Tom Cruise is talking to the young lady in the record store, the camera shows bad guy Lane (Sean Harris) occupying one of the listening booths.
Question: Why does Benji have to enter the facility at the same time Ethan is switching the security profile? It's more dramatic that way, but couldn't Benji have waited to enter until after he knew the profiles were switched?
Answer: He most likely could have waited, but as you pointed out, it's more dramatic that way. This is a movie and the action is choreographed for maximum dramatic and visual effect, timing, tension, continuity, audience attention, and character interaction. We're not supposed to overthink it.

They would want Benji to enter as soon as possible, as the security may notice eventually that there is something amiss. Still going in without bothering about confirmation seems unnecessarily risky.
