Could you please provide more information about this issue?

E.g. Browser / code example

Maybe are you sending multiple call at once with the same callbackName?

superagent.get('exampleURL')
      .use(superagentJSONP({ callbackParam: 'jsonp', callbackName: 'myCallbackName', timeout: 10000 }))
      .end(function(err, res){
        console.info(err, res)
      });

superagent.get('exampleURL')
      .use(superagentJSONP({ callbackParam: 'jsonp', callbackName: 'myCallbackName', timeout: 10000 }))
      .end(function(err, res){
        console.info(err, res)
      });

superagent.get('exampleURL')
      .use(superagentJSONP({ callbackParam: 'jsonp', callbackName: 'myCallbackName', timeout: 10000 }))
      .end(function(err, res){
        console.info(err, res)
      });

The plugin cancel callbackName window function after the request is ended.
If you use the same name on parallel calls only the first call will found the function stored in window.

I had the same issue, specifying the timeout worked me. The callback is being removed from window before it is called. Specifying the timeout option wasn't necessary in the prior version I was using. For a baseline, the response times range from 60ms to 150ms in my use case.

I had the same issue, providing .use(jsonp({timeout: 10000})) solved the issue. Thanks.
