Buyer: Is it possible to change the media seller in an existing contract?

On the left-hand side menu, select "Create Contract" under Buy.

For steps on creating a contract, use this Support Article.

Copy the data from the original contract and paste it into the new contract, if needed. You can use ctrl+c to copy and ctrl+v to paste.

After your new contract is created with your desired seller, you can now cancel the original contract that is under the incorrect media seller. To navigate to all contracts, select "Contracts" under "Buy".

Your contracts will now be listed, click on the three dots on the right-hand side of the contract you wish to delete with the incorrect seller. Click "Cancel".
