How can i change it? Earning 50% of each sale used before.
(Sorry for english)
It seems that You are not an exclusive author and as non-exclusive your rate is 33%. To change this – go to your SETTINGS and there is an EXCLUSIVITY OF YOUR ITEMS tab. Change it to be an exclusive author and You will start earning 50% and more. Unfortunatly it takes some time to process after You click the button, so be patient (imo around 1 month).
you must set up you account to Exclusive Author your dashboard -> my setting -> exclusivity of your items
