In the app when we are sending push notification with Big picture sometime the big picture are shown and sometimes we are seeing white background in place big picture.

The issue is random not a device/OS specific.

                                .setSummaryText(notificationData.getCleverTapMessage())
                                .bigPicture(bigPicture));
