Since yesterday, the data from the offer export is not up to date.
If you deleted the offer and created a new one between yesterday and today, we currently show your old offerid of the offer that has been deleted.
The process status from the offer update with a old offerid will end up in: [Offer not found] The offer [ID/UID: xxx] does not exists”.
A work around for this issue is Retrieve offer IDs using offers API for v3 and v4.
We are working hard to solve this issue
Since 17:00 is all the data up-to-date
