Adobe XD / Creative Cloud Versioning

Is versioning supported for Adobe XD files.

When viewing PSD and other file types on Creative Cloud (on the web / assets.adobe.com). I see an activity tab where I can view and restore older versions of the file.

I can see the tab on XD files created back in April 2017.

Currently I do not see the activity tab on Adobe XD files.

Should the Activity Tab be there? Is versioning supported? I am trying to determine if this is a firewall issue at my organization or if this is an XD bug.

Thanks
