[AoS / Thor / MCU] Where was Lady Sif during the events of Ragnarok and Dark World?

Ragnarok? Loki probably sent her somewhere far away in order to help maintain his cover as Odin.

The Dark World: She was right there, helping Thor and Loki escape from Asgard. She was last seen making a stand to delay the guards. Before that, she was with Thor during the fighting in Vanaheim.
