Glad to hear it. If anyone has Twitter perhaps they could retweet Core2TOM’s tweet. Credit goes to him.
@ioi_lukasz: Could do something with this as it looks like it’s the missing piece of the puzzle? It seems to be solving the issue for everyone who hasn’t found a solution up to now.
If remoting installing from the web site does not work. Just select a different game that you do not have installed or uninstall something and use the Install to my devices button. I did this with Control and it immediately pushed HITMAN 3 Access Pass: HITMAN 1 GOTY Upgrade and HITMAN 3 Access Pass: HITMAN 1 Complete First Season.
Basically use the web to push something else and you should see the Hitman stuff as well.
That’s great and it did work for me but what about Hitman 2 though? 
The Hitman 2 access pass was already waiting in my ‘ready to install’ part. I know a few other people have had issues with this as well.
I’ve tried a bunch of the suggestions here and I still can’t get the Hitman 1 levels to appear in 3 on Xbox.
I own Hitman 1 complete edition and Hitman 2 gold digitally. The Hitman 1 levels appear and work correctly in Hitman 2. I have purchased Hitman 3 standard and the Hitman 2 legacy pack always as owned but nothing I’ve tried is granting me ownership of any similar access pass for Hitman 1.
It still seems a bit unknown why some people don’t get ownership of the pass. I do wonder given the seemingly random nature of it suddenly showing up for some people if they are manually toggling it for the accounts of people without it whose posts here and on social media they see.
Though equally baffling once people do finally get it showing as owned is why they didn’t make the pass itself have any installable dlc that you could just install via the “install all” button on the access pass’ store page, but instead had it confer ownership of new downloadable content under the hitman 3 install manager which needs to be remotely pushed to become available in your manage game list.
Hi - I’m having issues with my Hitman 2 Access Pass. I had it before I uninstalled Hitman 3 but now not downloading. Have Hitman 1/2 Expansion Access Pass but Hitman 2 Access Pass asking for £54.99 even though I own Hitman 2 digitally. This is on Xbox Series X. Thanks.
Not sure if this has happened to others, but for some reason the Hitman 2016 and Hitman 2 levels have all disappeared from the game? It says I need to get Access again despite re-downloading both passes?
Not sure if anyone else has had this problem? I’m a bit behind with Hitman news at the minute so this might have already been mentioned.
This has only happened since the Season of Sloth update.
