Yes. As long as the existing affiliate didn’t already receive a commission payment, you are able to change who the affiliate is.
You can do this by going to Transactions, then clicking on the affiliate avatar. A new window will display to allow you to update who the affiliate should be.
Note: If there is a Subscription linked to that transaction, you will have to also update the subscription with the new affiliate. We automatically prompt you and provide a direct link to that subscription so you can easily update it.
