Yes

It's on Disney+ and not under the Marvel Cinematic Universe banner?

Wow, almost like the "Marvel Cinematic Universe" banner is just there to highlight the primary big Marvel Studios instalments in the MCU and not meant to encompass the entire continuity. I wonder who's been doubted for saying that for years...

(This is not directed at the original poster of this thread.)

It's under MCU for me.

Definitely. Now we should wait until next Friday for the Marvel Studios Legends on the Mandarin and the Ten Rings.

Just for the record, this is under the MCU banner now on Disney+

It is canon for certain.

Wait, what? They added the one shots?
