Certain filters will block events from displaying in your reports. Check these are disabled / removed to solve this issue.
Google Analytics will allow you to filter your view but sometimes the events we push are seen as bot traffic.
First check to see if we have processed any events successfully:
Analytics Amplifier: Account Settings >> View recent event logs here
Here you will see the 100 most recent processed events that have been pushed to Google Analytics:
Now check Google Analytics settings: First one to check is "Exclude all hits from known bots and spiders" is unticked on your view:
Note: once you have unticked this it will only apply for events going forward so give it a day or so for events to start showing.
You can also add your own custom filters. Also have a quick look here to see if anything else has been setup here that could be filtering the events from your view.
