Go to the Marvel Comics app (operated by Comixology) and sign in with your Marvel account credentials.
If you are an iOS user and don’t see your digital comics, once you have created a Marvel account and signed into the Marvel Comics app with your Marvel account credentials, you must next go to the store selection of the Marvel Comics app and add any item to your wish list. This will sync your digital library of comics and allow you to access your digital library in Marvel Unlimited. Note: Adding any item to your wish list is a required step to ensure your account is properly linked.
If you have any previous purchases made in the Marvel Comics app while not being signed into a Marvel account, you must select Restore Purchases from the dropdown menu at the top of the home page in the Marvel Comics app. This will link any Marvel digital comics bought while not signed into your Marvel account. Restoring Purchases will ensure that your digital comics are synced to your Marvel account so you can access them in the Marvel Unlimited app in the coming weeks.
Please make sure to download the Marvel Unlimited app, version 7.42 or later, in order to view your digital comic purchases/redeems in Marvel Unlimited. Once downloaded, you can log into the app here.
