I just seem to have been in some sort of penalty box for 48 hours.

In Fiddler, I see a request to (siteurl)/_vti_bin/client.svc/ProcessQuery with the following:

<Request AddExpandoFieldTypeSuffix="true" SchemaVersion="15.0.0.0" LibraryVersion="16.0.0.0"
    ApplicationName=".NET Library" xmlns="http://schemas.microsoft.com/sharepoint/clientquery/2009">

orchee Thanks for responding, I've already done the walkthroughs just to make sure. But I've been able to do this in the past. Not sure what's changed. I've asked some others on my team if they are able to do this, waiting to hear back.
