Why should a report owner be cautious about changing default behaviors for a report?

A report owner should be cautious about changing default behaviors because making such alterations can lead to confusion for users who expect certain interactions and functionalities. Default behaviors in Power BI reports are often designed based on common user experiences, allowing users to navigate and analyze data in a familiar way. When these defaults are modified, it may disrupt the intuitive flow that users rely on, making it harder for them to drill into the report and draw insights efficiently.

Users typically have pre-existing expectations based on their experiences with other reports and tools. If a report behaves unexpectedly—such as changes in how filters work, drill-through options, or data visual interactions—users may find themselves disoriented, leading to frustration and potentially hindering their analysis.

The other options present valid concerns; however, their implications might not directly relate to user experience in the same way. Changes to appearance or performance are certainly important, but the immediate impact of altered interactions—reflecting user expectations—takes precedence in ensuring a seamless user experience.
