I got a kinda odd one. I recently bought DLC for Destiny 2 PC and got my DLC code (I didn't purchase it from steam but another trusted seller) But I'm having a problem submitting the code. You see, I have cross-save on my destiny 2 account and at the moment I'm playing on xbox and mobile, Although I have cross save between all three platforms. I tried to use the code through steam but it's telling me I basically need to "Activate" the game... problem is I don't have access to an actually PC at the moment. How can I Activate the game on steam through mobile so I can use my DLC? Thanks for the help
