Codeless IAP - no google restore, no already owned message

I am trying to test codeless IAP for android.
Purchased OK first time through, but after reinstall there is no restore and when I click the IAPButton again there is no call of ProcessPurchase or OnPurchaseFailed so there is no feedback to the user and no restore.

Initial logcat on start up after reinstall:

There is ‘Unable to buy item’ and ‘Product purchased successfully’

What is happening, what can I do to fix?

Here’s one solution…
