I'm making chrome extension based on Chrome Identity API and I wanted to test existing extension using this API. Tried sample app from this repo (https://chrome.google.com/webstore/detail/identity-api-sample/oficlfehfenioickohognhdhmmcpceil) and it looks it's not working. After clicking "Sign in" button log says "Acquiring token..." and nothing happens. No error, nothing.
It looks like the fix has been applied in the chrome app sample folder 5adb0fc but not published it to the WebStore.
Will update it and let you know when it's done.
Thanks for reporting it!
