Oh that definitely I agree was wrong. Nothing in it really breaks canon what with all the timeline jumping and such both the show and movies did. Loki alone should have made S.H.I.E.L.D. canon

Maybe not completely. There were several references to AOS in Wandavision. For example, the Hydra Soap ad is believed to be a nod to the AOS Framework story line where Coulson was sure that Hydra was using soap to mess with everyone's memories. Also, the Darkhold from AOS which was taken to the dark dimension by Ghost Rider, was returned from there by Morgan Le Fay in the Runaways series. Somehow, Agnes Harkness took possession of it after that and it appeared prominently in Wandavision.

It always felt like it was trying to be canonical but no one else wanted it to be. It was the little brother desperate to join the older kids only to get ditched at every opportunity.

Which was annoying because most of the show was good, and all it would have taken is a tiny Easter egg to acknowledge it exists. As far as I know, the only thing we ever got was Jarvis in endgame being played by the same actor from Agent Carter.

It's kind of strange that the Netflix shows are the ones that got folded into canon when they basically ignored the rest of the MCU after Avengers. But I suppose that disconnect and the more narrow focus means there's a lot less to clean up to make it fit. That and the fact that they were popular enough for Disney to see them as valuable.

Thanks for the response, I'll check it out in that case. I've just been overwhelmed by a lot of Marvel stuff, I still haven't seen End Game or Infinity War because I haven't seen all the movies that tie into them.
