Pinnable taskpane action causing add-in installation problems

We're trying to install an add-in that makes use of the pinnable taskpane action introduced in version overrides 1.1.

The error reads "This app can't be installed. The manifest file doesn't conform to the schema definition. The element 'Action' in namespace 'http://schemas.microsoft.com/office/mailappversionoverrides/1.1' has invalid child element 'SupportsPinning' in namespace 'http://schemas.microsoft.com/office/mailappversionoverrides/1.1..."

The Exchange server version we're on is Exchange 2016 CU1.

Has anyone encountered this scenario before?

Sample of the manifest below...

<VersionOverrides xmlns="http://schemas.microsoft.com/office/mailappversionoverrides" xmlns:bt="http://schemas.microsoft.com/office/officeappbasictypes/1.0"
        xsi:type="VersionOverridesV1_0">

According to MSDN blog: Pinnable Taskpane in Outlook 2016 new VersionOverrides version 1.1 has to be added to an existing version 1.0. Your example manifest completely missing version 1.0 overrides. Please follow the example command-demo-manifest.xml to make new pinnable feature work.

EDIT: To clarify with VersionOverrides element, when implementing multiple versions, please refer to VersionOverrides element: Implementing multiple versions

Slava's answer is correct but could use a bit more explanation. The key line from the documentation is:

"The child VersionOverrides element does not inherit any values from the parent."

In your example schema you replicated the <hosts> element alone. In order to work properly, it must also replicate the <requirements> element from it's parent.

SupportsPinning was introduced in Exchange 2016 CU4 and that is why it does not work in CU1 for you.
