This usually means the subscription is tied to a different email than the one you’re currently logged in with.
Common reasons:
You signed up with a work or school email you no longer have access to
You used Google, Apple, or GitHub sign-in, which may have created an account under a different email than expected
There was a typo in the email at checkout
You purchased through PayPal, which may use a different email than your Icons8 login
To help us locate your account, contact support with any of the following: the last four digits of the charged card, the approximate date and amount of the charge, or your PayPal email.
