Once you use "standard Dashboards" and "interactive Dashboards" to show and analyze records in D365 you certainly will share them to all users.

As we use a specific custom designed card form of the work order to show the details of records, especially in interactive dashboard in the browser you expect that this card form will also shown in the mobile app.

Nevertheless, in the mobile app you can enable interactive dashboards but they will not use/ show the card form of the entity. This is a by design behavior as the support and product team of Microsoft told me. What you see in mobile when you use interactive dashboards is only the information which is in the field "name" and "modified on". It is shown in a simple not user friendly list.

If you use "standard dashboards" in mobile app it will use the card form you design.

Therefore, my suggestion is: Extend the functionality of interactive dashboards in mobile app that it will use the specific card form.
