After the new update on Halo MCC, I loaded into the main menu but it took like 10 minutes. Today Im loading in but it’s taking me half an hour. This started happening after the new update came out .
A ‘tip’ to make the loading fast is to go to the xbox home during it. It works for me, I don’t know why: after 10 seconds in the home, I go back to the game and it has just loaded.
