    The new credit usage report is great for showing what users burned in terms of credits over a month or week. However, the report deployed in the Sep 2020 AGOL release does not include credit usage for feature storage, file storage, and tile storage.  These missing categories make up 98% of our org's credit usage, so it doesn't help us much with looking for accounts that are using the most of our credits.  


    Also, I noticed that the date range at the top of the report is given in UNIX Epoch integer.  A date format that is both human readable and easy to parse with common BI date functions would be better, like ISO standard 8601.  So rather than Aug 1, 2020 UTC appearing as 1596240000, it would be 2020-08-01T00:00:00Z.
