hi, This is a really frustrating one because between Bungie and Microsoft, there's no way (so far) to submit a question about an issue like this. Maybe this will work: 1 - gifted "Season of the Witch Queen:Deluxe Edition" using Microsoft store (I had credits) which includes seasons 16-19; he redeemed it, I see a note in the account saying he did so. 2 - tried to play with my friend, it is telling him he needs to buy Season of Plunder, season #18 Quick edit - the odd thing was that my other friend and I played with him as a 3 person team last night and did the first level of Season of Plunder and we also played the six person activity, AND he got that loot cache from the H.E.L.M. So it *felt* like he had bought it but then we couldn't progress to further missions and he was being told to buy it when looking at the Season. Perhaps he just needs to play a bit on his own to force it a bit??) Thanks for any help!
