Over the weekend, we had an issue that impacted our data processing, Raw Data Export, the Validator, and Livestream. We have identified a potential cause and are working to resolve it fully. Once the data processing is fully caught up, things should return to normal. The primary use case for the Validator is to ensure your Custom Events are formatted and sent correctly during development. As a potential alternative, it is possible to use a network traffic analyzer to determine if your events are sent. We have a Knowledge Base article that goes over the process (for stand alone and mobile builds): https://support.unity3d.com/hc/en-us/articles/115002917683-Using-Charles-Proxy-with-Unity I apologize for any inconvenience these issues have caused. We are working to make sure issues like these don't impact our customers. I will update this thread when I have any additional details.
