If you are using a Frooition Storefront then the changes eBay are bringing in to the Stores will not take effect until later in 2018.
There is nothing that you need to do in order to get updated to the new eBay Store. Your Store subscription fee will not change as a result of these changes.
If you wish to upgrade your eBay Store before eBay rolls the changes out to you. You can follow these instructions:
- From your Storefront, go to "Manage Store" page or from Marketing tab on Seller Hub, Click "Edit Store", located under 'Manage your Store' section.
- Click "Custom Pages" link on the left navigation bar; if you don't see 'Custom Pages' link, you can skip the rest.
- If you have any "Active Pages", select 'Deactivate' for all of them.
- Under 'Store Homepage' section, select 'All your listings' and select apply.
