Click the Refresh button to manually trigger a refresh of your Discord memberships.
Check with the community if their Discord server is properly verified in Team Socials.
By clicking on a community, the option to set default mint wallets for all blockchains, a Twitter account, and a Discord account appears. These defaults will automatically be selected and submitted when you enter any raffle hosted by that team.
By scrolling down, the option to set a default Discord and Twitter appears.
