Excuse me, veterans, FB feedback has always been more than the actual conversion. Is it the amount deducted by advertisers or is my data too little?
Inaccurate return is normal. If you order without paying, one may be returned. Those who run e-commerce may be more accurate.
E-commerce also needs to make good system plug-ins in order for it to be accurate.
The deduction is also normal. Since last year, the return has not been accurate. Both should be available.
