The rows under 2 Per marketplace on the right of the product editor, and the marketplace icons on each Inventory row, show Closo's current state for each marketplace. A grey icon means the product isn't listed there yet or the marketplace isn't connected.
The five reasons
1. The marketplace isn't connected
Open Marketplaces and switch the missing one's toggle on (for eBay, click Connect Ebay).
2. Your session expired
Marketplace cookies last 30-90 days. Sign in to the marketplace in a normal tab and switch its toggle on again in Marketplaces; the row goes live again immediately after.
3. Required fields are missing
Each marketplace has different required fields — eBay item specifics, Mercari category, Vinted brand. The List dialog shows a Required fields box with what each marketplace still needs, and the editor's eBay requires for this category block lists the item specifics — the icon stays grey until they're filled.
4. The Closo extension is offline
If the Inventory page shows Extension not detected or Closo went to sleep, the extension lost its connection. Reopen the Closo tab — your tasks resume right away.
5. The marketplace is in a temporary cooldown
After a failure (rate limit, captcha, server error), Closo waits 5-10 minutes before retrying. The toggle reactivates automatically.
