getEmailActivityUserDetail data not matching using D30 with last 30days

Question

Hi, this is an urgent request using the getEmailActivityUserDetail api , data not matching using D30 withmanually looping through 30 days

example using period= 'D30' xxx user

send_count - 857
read_count - 1003
receive_count - 3631
username - xxx user

and looping through since date='2021-04-10' last 30 days for the same user

send_count - 736
read_count - 1192
receive_count - 3075
username - xxx user

and other problem we have using this api is , the data is 2 days behind and if its weekend its 4 days behind.

Although using D30 gives us accurate numbers , we need daily results so looping through last 30 days lot of data is missing and not matching. If you can identify the problem that would be really fantasctic, otherwise pls let us know we have to stop using it as it giving wrong data , cant really present our clients with data decripencies.
Please give us some response asap.
thanks
ravi

If you see issue consistently then cross check the results in your M365 security & compliance center and see if it matches or not. If you see issues consider opening a support ticket for further investigation.
