Buying DLC from Ubisoft is not accessible if you bought original game from Steam

[RazorSteel]

I bought the Assassin's Creed Syndicate season pass recently, and was mortified when their tech support told me I would have to buy it from steam since the DLC and original game licenses are incompatible. I was hoping steam would be able to do something about this. I'm not paying for DLC twice, especially not when it costs twice what I paid for it.

Thank you for contacting us, RazorSteel.

We are still the Ubisoft Support team on the forums here, you'd need to head through the Support Site to speak with the Steam Support. You can find this here

Dammit! That link just sends me to the beginning of the circle that led me to post here.
Sorry, steam is making this incredibly frustrating

Hello RazorSteel [Evo],

I can confirm this is correct unfortunately, DLC is not cross-compatible over launchers, you would need to purchase the DLC from where you also originally purchased the game from.

If you would like to reach out to Steam for a Steam bought product refund, you can do so here - https://help.steampowered.com/en/faqs/view/784C-923B-A4A1-C825

If you need to refund something bought from the Ubisoft Store, you can do so by following this guide here -
