The new global referral bonus policy is effective as of April 10, 2017.
You can use either 'as of' or 'from', but not 'as from'.
however, now is hard to track the time when the referral occured.
In this case, it is better to say:
"However, now it is difficult to track the exact date of referral."
I suggest to take referree’s start date 2017/5/8 as the cut point between the new policy and old policy. You can make the sentence a little more fluent with adjustments like this:
"I suggest to mark the referree's start date (2017/5/8) as the cutoff date between the old and new policy."
(In English, we usually say 'old and new' rather than 'new and old'.) 作者: vegasoul 時間: 2017-9-22 09:21 PM
The new global referral bonus policy is effective from April 10, 2017. A one-month grace period is recommended. The last date for the old policy will hence be May 8, 2017.
你有很多字也串錯了。例如 referee.
還有the old and the new policies應用複數。作者: rayyeh 時間: 2017-9-23 08:31 AM

The new global referral bonus policy is effective as from April 10, 2017, however now it is hard to track the time when the referral "was made". I suggest to take referree’s start date 2017/5/8 as the "cut off date" between the new policy and old policy. 作者: rayyeh 時間: 2018-7-14 09:24 AM
