`onPurchasesUpdated` received broadcast twice in a normal billing flow

I noticed this issue starts to surface since two days ago. I am launching a normal billing flow with :

BillingFlowParams flowParams = BillingFlowParams.newBuilder().setSku(sku).setType(BillingClient.SkuType.INAPP).build();
billingClient.launchBillingFlow((Activity) context, flowParams);

When the billing flow is successful, we are notified through onPurchasesUpdated twice. When I debugged, I found that BillingBroadcastReceiver received two broadcasts and they have the same content (resultCode and Purchase). Previously, onPurchasesUpdated is only notified once.

Updating to the latest library : com.android.billingclient:billing:1.0 doesn’t resolve this issue. From the server logs, it seems like more and more user are encountering this issue.

I would like to verify if this is a change in Google Play Service? Or some buggy behaviour which the team is resolving? Since updating the newly released library doesn’t resolve the issue, do you recommend having a workaround on the client side? Thanks.
