Well, to this I would argue that they also place Thor TDW right after Avengers, which, although not wrong, isn't where the majority of the film takes place. So I'm not sure I trust their Loki placement...yet...I would just put it immediately following Endgame. If you look at the timeline order on Disney Plus, that's where they place it.
As previously stated, he thinks that the canon tie-in comics are non-canon.
It would merely mean that she worked for TVA for hundreds of years which doesn't tell us much, especially since "time works differently here".Something I feel we've overlooked regarding the placement of the TVA on the timeline:
Sylvie in episode 3: (speaking to Loki regarding C-20's recalled memory) "I had to use a memory from hundreds of years ago, before she worked for the TVA."
So this would place the TVA scenes ~2300.
