By default the Recolize product feed is generated each night. Additionally you can also set another time in the configuration section of the Magento extension.

If the Recolize product feed in Magento is not up-to-date there are a couple of things to check:

  1. Is the Magento cron job set up correctly? According to Magento it should run every 5 minutes.
  2. Has the Recolize cron job run successfully last night? Therefore e.g. you can check the cron_schedule table of your Magento installation.
