When on your laptop, is the "Recommended Tickets" filter turned off?
As @matti58 mentioned, you may want to check to see if the filters are off as that may cause the listing not to be visible. Also, if you're relying on price matching to confirm your listing, that will also change since dynamic markdowns can cause the price to be lower on the site than what you had listed. If your listing is lower due to the dynamic price markdown, you will still be paid based on the price you requested when creating the listing.
