# I paid for Pro but it is not active

> Restart the app, sign in with the account you bought with and use Restore Subscription in Settings. If that fails, send us your receipt.

If you bought Knowunity Pro but the app still shows the free plan, one of these steps almost always fixes it.

## 1. Restart the app

Close Knowunity completely, wait a few seconds and open it again.

## 2. Check you are on the right account

Pro belongs to the Knowunity account that was signed in when you bought it. Open your profile and check the username. If you have more than one account, sign out and sign in with the account you used at checkout.

## 3. Restore your subscription

1. Open your profile and tap the gear icon to open **Settings**.
2. In the **Subscription** section, tap **Restore Subscription**.
3. Wait for the confirmation.

This asks the App Store or Google Play to link your purchase to your current account again.

## If you bought on the website

Make sure you are signed in to the app with the same email address you used at checkout. Pro bought on the website activates on that account.

## Still not working?

If you see **The subscription is already in use on another account**, the store purchase is linked to a different Knowunity account. [Contact support](https://knowunity.com/support) and include:

- your username or the email address of your account,
- where you bought Pro (App Store, Google Play or website),
- a screenshot of the receipt, including the date and amount.

We will find the purchase and link it to the right account.
