What If... Captain Carter Were the First Avenger? - S1-E1
Other mistake: The premise of the first episode is flawed; "a single choice" should make the difference, the choice being identified as Ms. Carter not leaving the room to get in the observation booth. But in the normal timeline the booth is exactly where all the other characters were. In this reality everyone else is downstairs, with the German spy that inexplicably sets the bomb early. If anything, it's his bizarre, suicidal choice that matters.
Suggested correction: Except it was her decision to not leave the room that delayed the procedure and gave Heinz Kruger the chance to attack. And with her in the room, she is now given the chance to volunteer to take the serum.
How did her staying delay the procedure? Besides, in OTL the spy only triggered the bomb after he saw the procedure succeed, to know it works before stealing it.
Other mistake: Supposedly the one difference between this universe and the movie canon is that Janet was infected by a zombie virus before she was saved by Hank and Scott. However, in the original movie Janet actively led them to her by 'possessing' Scott and while intelligent, these Marvel zombies can't communicate. Also, Vision is settled in Camp Leigh, which appears to be in perfect shape despite being hit by a missile powerful enough to penetrate in the bunker in Winter Soldier.
Suggested correction: As I said in my other correction, differences between the MCU movies and this show cannot count as mistakes, since they are showing us different universes with different outcomes. Just because Janet lead Scott to them in the movie doesn't mean that's what happened in the show's universe. Same with the "Winter Soldier" discrepancy.
Without Janet leading them, they wouldn't have even learned about her existence based on what was shown in Antman and The Wasp, and they show the laboratory scene pan out as it did in the movie. Althought technically she could have been infected by the zombie virus in the minutes it took them to get to her inside the Quantum Realm. You realise that it's flimsy and it relies on people essentially not remembering the movie, though.

Factual error: When Stark starts telling about the Tesseract, the colonel shows surprise that Nazis were in Norway. Peggy answers with "Close. HYDRA." The scene is set in 1943, and Norway had been occupied by Nazi Germany for three years already. Them being in Tønsberg should not come as a great surprise to an Allied commander. (00:07:10)
Suggested correction: I feel like this falls under the "Not a mistake because it's an alternate universe" umbrella. We're in an entirely different universe with a different timeline in this episode.
The show also makes a point that the only difference should be the minor choices or events befalling the MCU characters, and how these minor things have huge consequences for them, basically creating a new alternate timeline. Basic world history before these events is not affected by the new timeline.
Basic, unaltered world history does not apply with this because we are talking about an alternate WWII from the beginning. One with Schmitt/Red Skull as propaganda minister of Hitler, Hydra superseding the SS, super soldier serum, Stark tech, the Tesseract, etc. It is not WWII as we know it, even without the "what if."

Factual error: In the intro, we are shown how Nazi Germany spreads across Europe - but after showing Denmark being conquered, it is shown to start spreading across Sweden. Sweden was never occupied by the Germans in WWII.

Suggested correction: The black spot spreading is not representing territory physically conquered by the Nazis, but more of their sphere of influence expanding. It is a steady spread and not a true representation of the war's progression. You can notice how Switzerland is also covered by the black, even though it was neutral during the war. Nor was Italy conquered, but their ally instead.
