There are four ways to check whether your comfort bid was placed in an auction:
1. You will receive an automatic notification in the email address of the bid creator;
2. Your bid will be displayed in your activity feed up to 30 days after the placement;
3. Your bid will be displayed in the auction page (go to "Transport," then "Auction" and, finally, search for the auction in question).
4. For older bids, you can search for the auction in the "Reporting" section (go to "Reporting," then "Short and Long Term Auctions" and use the filter to find the auction in question).
