I just upgraded to affiliates pro. I tried to set a referral rate of 0.075 (i.e. 7.5%), but when I save the field changes to 0.07
I tried adding the filter affiliates_referral_amount_decimals in my functions.php as described, but this doesn’t seem to let me save a value of 0.075.
This was possible in the basic version of affiliates. How can I get this back?
