AndyMal Thanks for using the Modern Commanding. Clarifying your questions. 1. Correct, since you added a button without any rules and always shows by setting visibility to “Show.” It should be visible to all users unless there is any rule. Can you provide more details such as the name(labels) of the new buttons, sessionId of the repro where buttons are not visible, and also a screenshot of the command checker rules evaluation of the hidden buttons? 2. Since no rules exist for this new button, the command checker is working as expected. Please follow more here for documentation. docs.microsoft.com/…/command-designer-overview 3. I think so.
