 - Ensure `UID2_BASE_URL` uses `host.docker.internal:8080` not `localhost:8080`
 
-### Token Doesn't Persist
-
-- Check browser localStorage for `__uid2_advertising_token` key
-- Verify no browser extensions are clearing storage
-- Check browser console for JavaScript errors

 ### Prebid Doesn't Have the UID2
 
 Run `pbjs.getUserIds()` in console:
 - If empty or missing `uid2`, check console for Prebid errors
 - Verify Prebid.js loaded correctly (check Network tab)
 - Ensure `setPrebidConfig()` is being called after token generation
