Legacy app warning message

Posted on by Elaine B

I've installed D365 Sales in a new production environment (as from a previous reply you cannot install D365 on a default environment).

I now see the D365 icons in my left hand menus but on opening it I get the Power Apps screen that says at the top: Dynamics 365 - custom.

Also a warning message that says 'This is a legacy app and might have features or customizations that aren’t supported in Unified Interface. For best results, create a model-driven app for Unified Interface'

Can I use D365 anyway - or will I need to create a model-driven app?

Thanks

Correct you can still use the D365 Sales app but will continue to see the message. docs.microsoft.com/.../update-apps-to-unified-interface

Hello Elaine,

To have the best performance using Unified Interface it is advised to create a model-driven app from the scratch instead of using the "Dynamics 365 - custom", or use one of the other predefined apps that are part of the installation (Sales Hub, Customer Service Hub, etc.).

Please check this official article explaining how to build you first model-drive app: https://docs.microsoft.com/en-us/powerapps/maker/model-driven-apps/build-first-model-driven-app

Hope this helps you.
