Azure Migrate | CSV import in Preview | keeps spinning without working

I am wondering if anyone has managed to get the Azure Migrate CSV file import feature to work correctly?

It is documented here

https://docs.microsoft.com/en-us/azure/migrate/tutorial-assess-import

I imported 20 servers about 4 days back, and it was supposed to let me create an assessment 10 mins after import was complete. It's still spinning with "Discovery is in process". Is there a way to look at the logs under the hood to figure out what's wrong?
