There are two possibilities:

1. Currently, you either have to wait for the hourly sync to run or delete & re-add the product to the offer. In the near future, a manual sync option will be added.

2. Make sure the product is set to be visible on the "Online Store" sales channel. If a product is in stock but not available on the Online store, it can't be redeemed.
