Umber Winged Darkness Set not accessible

I bought the ultimate edition of Diablo 4, which includes the Umber Winged Darkness armor cosmetic. I recently started playing Diablo Immortal and this item should have still been available to me. Blizzard support said to report a bug here, that my account shows as having gotten the armor set, but it isn’t actually in my inventory.

Turns out, there are at least 2 other posts of bug reports with this issue:
I can’t find the Umber Winged Darkness Cosmetics Set in Diablo Imortal
Free Cosmetic in Diablo Immortal from purchasing Diablo 4

Could we please get some technical support to check out why this has disappeared.

In addition to a description of the bug you are reporting, please provide:

Device Type: iOS, PC
Device Model: iPhone, Ipad, and PC
Device Operating System: windows 11, iOS 17
Diablo Immortal App Version:

Do we have any more information on this? Having the same issue
