Following the https://help.bungie.net/hc/en-us/articles/360049498571-Prime-Gaming-Support-for-Destiny-2 troubleshooting guidelines, I'm here to post this thread.
I've verified that I do have my rewards in https://www.bungie.net/rewardshistory, and tried relinking all steam/amazon/prime/bungie accounts but still don't see my rewards from Amanda (but they are visible in DIM).
I'm out of steps to try, would sincerely prefer some help.
