I paid for an Ultimate Yearly Subscription, but app says "no license found"

I paid Google Play for an “Ultimate Yearly Subscription” to Avast that is meant to cover many devices.
When I download the app, I then sign in with the same Google account that I used to pay for this subscription.
But then the app says “no license found” - so I’m paying Google Play a significant amount of money and getting nothing from it.
Am I doing something wrong?
Cheers, Jamie

I’m an Avast User like you, so I’m not sure if this was a purchase on the Google Play store if it only applies to multiple android devices.

Hi Jamie33, this could be related to an issue where some customers cannot activate the subscription. We’re working on a fix (it should be released today), but in the meantime, you can activate your subscription using your activation code.
I sent you your activation code via personal message here on the Forum.
Please let me know if it worked.

We just released the fix addressing activation issues in Android Cleanup. It should be installed automatically, but you can also trigger this update in Google Play Store.
Once the new update is installed, the activation should work again.
