MobileExcelWebAccess Feature -Site Template Error

I just got off the phone with Microsoft regarding this issue. They provided me with a script that i will post below. Prior to running the script run Powershell online Management Shell as Administrator, download and install SharePoint Online Client Components SDK:

Copy the Feature ID from the error message

Then copy paste the following script (Modified with your info as noted):

$host.Runspace.ThreadOptions = "ReuseThread"

function Enable-SPOFeature

{
