  • Dialogs
    • "A link child dialog can’t be an intermediate step. You might try to split a complex dialog into child dialogs and invoke all of those child dialogs from a parent dialog. However, that is not supported in this release.

      There’s a limit to the number of nested steps you can use in a dialog. The limit depends on the browser you’re using and isn’t a limit in Microsoft Dynamics 365. The nested steps are rendered in the browser as nested tables. Some browsers support more levels of nested tables than others. If the workflow designer becomes grayed out where you can’t add additional nested steps to your dialog, try the following workarounds:

      • Redesign the dialog to use fewer nested steps.

      • Add a child dialog to reduce the number of steps in the parent dialog.

      • Use a different browser."
