I would like to get the # of unsubscribes per month for a specific child BU
(1) I queried _Unsubscribe where EventDate is within the desired period
(2) I queried _ListSubscribers where DateUnsubscribed is within the desired period
--> 1 and 2 return different results:
for example 5k and the other 10k, so the difference is huge
--> If I query ENT._Subscribers, this might be the real count, but this is for all BUs and I need to count the unsubscribes for a specific BU.
In short, I have different counts and seems none is correct.
