 This topic provides guidelines on working with embedded canvas apps as well as helpful tips to troubleshoot any issues you might encounter.
 
 -	Embedded canvas apps are only supported with Unified Interface model-driven apps.
--	You can only enable one embedded canvas app per form. 
-     - You can have multiple embedded canvas apps added to the form but can only enable one at a time.
-     - If you try to enable more than one embedded canvas app on a model-driven form you will get a message that reads “Only one canvas app can be enabled on a form.”
-     - To enable or disable an embedded canvas app see [Enable an embedded canvas app](#enable-an-embedded-canvas-app) and [Disable an embedded canvas app](#disable-an-embedded-canvas-app).
+-	You can only enable three embedded canvas apps for each form with Web, and one for Tablet and Phone client types. 
+-	You can have multiple embedded canvas apps added to the form, but can only enable three at a time for Web and one at a time for Tablet and Phone client types. 
+-	If you try to enable more than three embedded canvas apps with the Web client type on a model-driven app form you will get the message "You have more than three canvas apps with Web form factor, the maximum is three for this form factor. The number of canvas apps are limited to three for Web and one for Tablet and Phone form factors."
+   - To enable or disable an embedded canvas app see [Enable an embedded canvas app](#enable-an-embedded-canvas-app) and [Disable an embedded canvas app](#disable-an-embedded-canvas-app).
+-	We recommend that you have a single embedded canvas app for each form tab.
 -	When adding an embedded canvas app to a model-driven form always use a required field that is guaranteed to have a value. If your field does not have a value your embedded canvas app will not refresh in response to any change in data on the host model-driven form.
 -	Publishing a model-driven form does not also publish the embedded canvas app.
      - Embedded canvas apps need to be published independent of the host model-driven form. More information: [Publish an app](../canvas-apps/save-publish-app.md#publish-an-app).
