What do the error messages when buying Pro in the app mean?

If something goes wrong when you open the Pro plans or try to buy Pro in the app, a screen explains what happened. Find the title you see below.

If the same problem happens again, the screen keeps its title and says Still not working? Contact support and we'll help you sort it out. Tap Support and include a screenshot of the screen.

Prices didn't load

The App Store or Google Play did not send the Pro prices to the app. Nothing was charged.

• Tap Try Again, or tap Continue for free and come back later.
• Check that you are signed in to the App Store or Google Play and that the store app is up to date.

This Purchase Isn't Allowed

Your device or store account blocks the purchase, for example through parental controls. It can appear as soon as you open the Pro plans or after you tap to buy. Tap Got it. Trying again does not help until the setting is changed. See My payment failed or I cannot complete the purchase.

This offer isn't available

You may already have Pro, or you have used this offer before, for example a free trial. Tap Got it.

• Check your subscriptions in your Apple Account settings or in Google Play under Payments and subscriptions.
• If you already pay for Pro but the app shows the free plan, see I paid for Pro but it is not active.

The App Store isn't responding / Google Play isn't responding

The store could not finish the purchase. Wait a few minutes and tap Try Again. Do not buy again before you have checked whether Pro is active.

Network Issue

The app lost the connection. Check your internet connection and tap Try Again.

That didn't work

Something went wrong with the purchase. Tap Try Again. If it keeps happening, contact support through the support form.

Give It a Few Minutes

The store is waiting for you to finish a step, such as a confirmation from your bank or a parent. Follow the instructions in the store's payment pop-up, then come back to the app. Tap OK. Do not buy again.

Buy on the website instead

If buying in the app keeps failing, sign in on knowunity.com with the same account and buy there. Pro activates on your account and works in the app as well.
