Purchasing through Google Play

I just paid playstore €6.99 for a better version of ccleaner.I have received a notification from Paypal saying I paid but I haven't got a code to upgrade, what can I do please?

Moved to ccleaner android board

I believe that when you buy CCleaner Android from the google playstore it knows that you have paid and registers the product for you, so there is no further key/code to enter.

(If you download the Free version it knows you haven't paid so doesn't register it).
