Why is microsoft making me repurchase dlcs?

You gotta be my long lost twin because the EXACT same thing happened to me. I own every DLC in destiny 2 but only beyond light, Forsaken, and Shadowkeep won't work. Almost cried when I saw that a had to repurchase the DLC's they be expensive!

That's indeed odd but that may have caused the issue, the DLC was redeemed on the wrong account.

for some reason on my other account, I go to purchases no purchases are made but for some reason, it says owned on the other account but I never redeemed or purchased it on that account because there's no Bungie account connected to it and I used to use the dlcs all the time its like they transferred accounts because some dlcs are on one account and others are on another.

Thank you so much for the detailed information, no worries, even if it's a redeemed code it should still be visible. If it's not showing from there please check all Microsoft accounts that you own.

I would like to clarify, you've mentioned a different account which you said that it was stated as "owned" from there, were you able to check the order history of that account?
