Please let us know below if you have questions, feature suggestions, or any other feedback!
As the blog post mentions, we will continue to iterate on this feature in the months to come. The list below details the planned improvements, and provides links to their respective UserVoice pages. We encourage you to cast your vote on UserVoice to help us prioritize our next steps!
RE Yoshihiro - we are looking into this. To help us prioritize, please feel free to create a topic on ideas.powerbi.com and submit your ideas there.
RE cwebb22 - we are aware of all the issues you mentioned, and are looking to address them during the course of public preview. Rest assured that our goal is that you'll get a timestamp in the right timezone, and that the report pages render with no issues in the email.
RE OneWithQuestion - with respect to security: only users who have access to the report in Power BI will be able to subscribe themselves. If the user loses access to the report, the subscriptions will cease. Subscriptions will honor the RLS configuration for the user that set it up.
A very helpful feature would be a option to SELECT the time that the email is sent. Some of our reports are refreshed multiple times throughout the day but the most meaningful to see in an email report would be the data at close of business. As it is currently configured, the email report is sent at the first instance of refresh which is not entirely what we need. Thanks for listening!
