Analytics custom events unreliable in WebGL

I'm having trouble with custom analytics events in WebGL builds. Standard events are logging fine in the dashboard, but custom events are logged only between 0%-10% of the time. I did a test yesterday with 90 custom events with 4 different players on 4 different machines in Chrome, Safari, and Firefox with different privacy settings. The Unity dashboard only picked up 2 out of the 90 events.

These events are registering in the validator, and some (most) standard events were logged for those sessions. I would normally think that something must be wrong with our implementation, but clearly Unity Analytics is picking up some custom events.

Can anyone help?

 

Processing for events in the Dashboard can take 8-16 hours to process, sometimes twice that long if we have a processing delay. Please open a support ticket and we can check our database https://analytics.cloud.unity3d.com/support

 

Yes, it's been 24 hours. And I've tested this before. I'll open a support ticket.

 

Just heard from engineering that we are currently experiencing delays
