Hi all, I just created a JavaScript Source with a Mixpanel destination, injected Analytics.js in my web app, it was easy. However everything looked right in the segment side, but nothing in the Mixpanel. Here's what I've got

1. I can see every page or track event in the Segment Source Debugger, but there was nothing in Mixpanel live view or insights
2. I can successfully send an event via Segment Event Tester, there was corresponding event in Mixpanel at that time

I just copied Segment snippet and used default Mixpanel destination configuration. I've no idea what's happening, any help or how to troubleshoot then?

btw, I've noticed there's no api-mixpanel call in Chrome network

thanks
