 + **Triggers**: While all triggers are fully supported in a Flex Consumption plan, the Blob storage trigger only supports the [Event Grid source](./functions-event-grid-blob-trigger.md). Non-C# function apps must use version `[4.0.0, 5.0.0)` of the [extension bundle](./extension-bundles.md), or a later version. 
 + **Regions**: Not all regions are currently supported. To learn more, see [View currently supported regions](flex-consumption-how-to.md#view-currently-supported-regions).
 + **Deployments**: Deployment slots aren't currently supported.
++ **Proxies**: Functions Proxies aren't supported.
 + **Scale**: The lowest maximum scale is currently `40`. The highest currently supported value is `1000`. 
 + **Managed dependencies**: [Managed dependencies in PowerShell](functions-reference-powershell.md#managed-dependencies-feature) aren't supported by Flex Consumption. You must instead [upload modules with app content](functions-reference-powershell.md#including-modules-in-app-content).
 + **Diagnostic settings**: Diagnostic settings aren't currently supported.
