Thanks so much for reaching out!
I cannot replicate the issue that you are experiencing, though we are having issues with our Facebook API so that may be part of the issue.
Can you try connecting again and let me know what you see?
Also, can you try removing your Event Aggregator license and add it back in, and then refresh your connection?
Also, can you enable and check the Event Log under Events < Help to see if you see anything unusual?
Right under that is your Event Aggregator Status. Can you take a screenshot of what you see there?
Let me know if you have any other questions in the meantime!
Thanks,
Jaime
