Fix a gate check that fails
Run the test, fix the one thing it flags.
- Go to Settings → Extension → Run test.
- It checks that the extension is installed and connected, that the background check is scheduled, and that a logged-in ASIN.so tab can be reached.
- Fix what it flags. Most often: sign in to your US Seller Central, or reinstall the extension and open it once to log in.
- Back in the Gate Check panel, click Recheck unknowns & errors.
Note: No extension installed? The Gate Check panel says so at the top. Install it.
