PurchaseResult was returning my purchases with acknowledge as false. Using the following code, managed to fix the issue.

for (Purchase purchase: purchasesResult.getPurchasesList()) {
                AcknowledgePurchaseParams acknowledgePurchaseParams =
                        AcknowledgePurchaseParams.newBuilder()
                                .setPurchaseToken(purchase.getPurchaseToken())
                                .build();
                acknowledgePurchaseParams.getDeveloperPayload();

                AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener = new AcknowledgePurchaseResponseListener() {
                    @Override
                    public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
                        BillingResult billingResult1 = billingResult;
                    }

                };

                mBillingClient.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);
            }
