'Push notification delivery event report is not updated in Big Query

I have enabled firebase cloud message delivery report in my project.

Delivery data report is updated properly but still most of the notification event is in "MESSAGE_ACCEPTED" stage.

In documentations, it says logs processing starts every day at 4:00AM PDT. It then takes 6-10h to complete, and usually the BQ dataset is exported shortly after.

There will be total 39K records in which 25k records event is in "MESSAGE_ACCEPTED" and 4k records in "MESSAGE_DELIVERED" stage.

Most of "MESSAGE_ACCEPTED" events is not updated. It still in that event for more than six days.

Kindly say when event records are updated? Is it delivered to users or failed ?
