In the July 2025 Power BI update, the Shape formatting option was removed from the Button Slicer visual. This change has significantly impacted the ability to customize the appearance of slicers, especially for users who rely on rounded or pill-style buttons for consistent UX design.
While layout and style settings (e.g., Card vs Table) remain, they do not offer the same level of visual control previously available through the Shape dropdown or border radius settings. Existing reports still retain their shaped buttons, which confirms that the underlying formatting logic is still supported — it's just no longer exposed in the UI.
This change:
- Reduces visual flexibility for designers.
- Breaks consistency with existing reports.
- Removes a feature that was widely used and appreciated.
Request: Please consider restoring the Shape formatting option or providing an alternative method (e.g., via theme JSON or advanced formatting) to control button shape directly. This is a small but important feature for maintaining visual polish and user experience in dashboards.
Thank you for your continued improvements to Power BI — this feedback comes from a place of appreciation and a desire to keep the platform as flexible and powerful as possible.

If the layout is set to "Tiles" then the option appears ... if it's set to Table then it disappears. I can't seem to make it work with the JSON. I've looked at the schema, tried many things but the options do not seem to take.
