Closo's Crosslister shows a listing's state on the marketplace icon of the product row: a spinner while in progress, a green check once live, red if it failed (click it for the reason and Retry on <Market>). The spinner is where the extension hands the payload to the marketplace's web client. 90% of stuck listings are stuck here.
Tell if it's actually stuck
A listing is stuck if its marketplace icon has been spinning for more than 8 minutes and the Inventory page shows Extension connected.
Fixes, in order
Try these one at a time. Most sellers get unblocked at step 2.
1. Confirm the marketplace is connected
2. Retry the failed listings in bulk
3. Clear the marketplace's cookies
4. Contact support
Why this happens
Marketplaces don't expose a public listing API — Closo drives their web client through your browser via the extension. Network blips, captchas, and silent logouts are the three usual culprits.

Chrome usually updates on its own; open chrome://extensions and click Update to force it.
