onPurchasesUpdated not called for pending purchase success

I have updated my application to use v2.1.0 (from an earlier 2.0.1 release) of the android play billing library and I am no longer receiving purchase updates on completion of a pending purchase.

I construct my billing client setting the listener to the current class, that implements PurchasesUpdatedListener:

billingClient = BillingClient.newBuilder( getActivity() )
        .setListener( this )
        .enablePendingPurchases()
        .build();

I then launch a purchase and use the “slow test card approves after a few minutes”

BillingFlowParams.Builder purchaseParamsBuilder = BillingFlowParams.newBuilder()
        .setSkuDetails( product );

billingClient.launchBillingFlow( getActivity(), purchaseParamsBuilder.build() );

My listener gets called after this indicating the purchase is pending:

@Override
public void onPurchasesUpdated( BillingResult billingResult, List<Purchase> purchases )
{
    int responseCode = billingResult.getResponseCode();
    if (responseCode == BillingClient.BillingResponseCode.OK)
    {
        // I get to here with a Purchase.PurchaseState.PENDING 
    }
}

However this listener does NOT get called when the purchase completes. I leave the application open and I see the notification from the play store saying the purchase was successful in the notification bar.

If I query the purchases manually after this notification I can get the updated purchase however this doesn’t seem like a valid approach for handling the purchase.

Does anyone know what I am doing wrong or has this process changed?
