Hello,
The above EAP is enabled on our sandbox instance and I've performed some tests. I was advised by support to post one of the findings here and seek advise:
Is it expected that I am able to avail of the 500,000 rows export only via the query builder and not via a dashboard? I placed a test query on a dashboard and set the default time range to something which would cause it to fail loading due to result size (“Results are too large to load”) but I would have expected to still receive the full result (under 500,000 rows) if I schedule the dash to deliver via e-mail. Instead I am only receiving an empty Excel file (claiming to be corrupted, mind you).
