How to update the infoblock for unloading from 1s?

Question

1C-Bitrix

Tell me, this is the situation. The site was configured to update the infoblock for uploading from 1C.Advertisement, but it has not been working for a long time. I need to restore the functionality of the exchange between 1s.bitrix and 1s.advertising, reflect only relevant information in the infoblock.
Where to begin?

Click the "Make Exchange" button. At least describe what you can't do.
