An error message at subscribing means that your Apple ID is already associated with a subscription on a different account. Each Apple ID can only be associated with one SALT account and one subscription at a time.
If you’ve created a new SALT account and want to subscribe to SALT Premium, you need to make sure that you’ve permanently deleted your old SALT account first. Deleting your account will permanently delete your matches, messages and other information associated with the account.
To delete your old SALT account:
- Sign in to the account you want to delete.
- Tap Home
- Tap Settings
- Tap Account
- Tap Delete my account
