If you ordered Sequencing, you can find your Sequenced images in the Collections tab. If you'd like to see all images (unsequenced), just click 'All Photographs' in the Catalog tab! Both the Collections and Catalog tabs can be found in the Navigator panel on the left side in your Lightroom Catalog.
If you are still not seeing your Sequenced images after following these instructions, please reach out to customer support with some screenshots of what you're seeing so they can assist you further!
