June 25th 2018 Update: There is no longer an option for sellers to refresh their RSS Feed. See what you can do instead here.
What is an RSS Feed?
How to reset your RSS Feed
Step 2: Toggle on "Don't activate your Fixed Price listings via RSS" and click Apply
Step 3: Wait. Waiting overnight is best, but people reccomend waiting for at least 6 hours before....
Step 4: Revisit the RSS Feed page and reactivate your RSS Feed.
Step 5: Sit back and reap the rewards of increased sales!
Now it's worth noting that this method is not fool proof. It's effects are temporary and it only refreshes the first 100 listings in your store. For this reason, we recommend refreshing your RSS Feed every couple weeks! Don't get too refresh happy however as an established feed is necessary for your listing to show up on google, in ads, etc.
