Hey there! Do you share your Amazon Prime account with anyone else? If so, do they play Destiny 2 and do they also sign up for this program? Have you tried logging in and out of the game to see if anything changes? To confirm, you've double-checked that the Gear Drop has been claimed on the Twitch Prime site? If you go into your Bungie account Settings and click "Accounts & Linking," do you see Twitch Prime at the bottom of the page under the "Authorized Applications" sections? Have you claimed your reward in your [url=https://www.bungie.net/7/en/Codes/Partners]Partner Rewards section[/url]? You also will not be able to claim previous loot drops as they are no longer available. Loot drops are monthly exclusive.
