Undo a Proposal
If you've scheduled a Proposal and it has not yet been delivered, clicking Undo on the Buyer's bar on the Recommendations page will allow you to cancel the delivery. The held credits will be returned to you after 14 days.

If the proposal has already been delivered, you can Recall it by going into your Proposal History.
Note: If the Buyer has already viewed the Proposal, the credits spent will not be returned.
In the Proposal History panel, click on the 3 dot icon to open a menu and select "Recall".
Click "Yes" on the prompt and the Proposal will be recalled. After 14 days your credits will be returned to you.
