Hi, I believe the problem is not on AppDynamics side. I just tested and inserted an email address into the string field and it shows correctly
Here is my sample Curl populating the data, which works. Can you try and manually post to analytics and see if it works, might be power automate which doesn't format the email address correctly perhaps?
curl -X POST "https://xxxxxxx/events/publish/TEST" -H "X-Events-API-AccountName:xxxxxxxx" -H "X-Events-API-Key:xxxxxx" -H "Content-type: application/vnd.appd.events+json;v=2" -d '[{"expirationDateTime": 1597135561333, "appleId": "test@test.com", "DaysLeft": "176"}]'
