Is there a way to see events firing as you test the app? I know there is "Live View", but there is a significant delay on seeing the events.
This week we had a small blip in which some events would skip the live view report. However, no events were dropped and each of these events were stored on our end and accessible in all core Mixpanel reports. You should now be able to see all new events tracked in your Live View report.
This should be the best way to test if your events are firing, and without significant delay. Are you still experiencing an issue with this?
