Upgrading Tier (Sku) via Set-AzureRmAnalysisServicesServer not working - powershell

Question

I want to upscale and downscale my Azure Analysis Services with PowerShell (Automation Runbook), but changing the Tier (Sku) doesn't seem to work. However there are no errors. Any suggestions?
# PowerShell code
# Connect to a connection to get TenantId and SubscriptionId
$Connection = Get-AutomationConnection -Name "AzureRunAsConnection"
$TenantId = $Connection.TenantId
$SubscriptionId = $Connection.SubscriptionId
# Get the service principal credentials connected to the automation account.
$null = $SPCredential = Get-AutomationPSCredential -Name "SSISJoost"
# Login to Azure ($null is to prevent output, since Out-Null doesn't work in Azure)
Write-Output "Login to Azure using automation account 'SSISJoost'."
$null = Login-AzureRmAccount -TenantId $TenantId -SubscriptionId $SubscriptionId -Credential $SPCredential
# Select the correct subscription
Write-Output "Selecting subscription '$($SubscriptionId)'."
$null = Select-AzureRmSubscription -SubscriptionID $SubscriptionId
# Get variable values
$ResourceGroupName = Get-AutomationVariable -Name 'ResourceGroupName'
$AnalysisServerName = Get-AutomationVariable -Name 'AnalysisServerName'
# Get old status (for testing/logging purpose only)
$OldAsSetting = Get-AzureRmAnalysisServicesServer -ResourceGroupName $ResourceGroupName -Name $AnalysisServerName
try
{
# changing tier
Write-Output "Upgrade $($AnalysisServerName) to S1. Current tier: $($OldAsSetting.Sku.Name)"
Set-AzureRmAnalysisServicesServer -ResourceGroupName $ResourceGroupName -Name $AnalysisServerName -Sku "S1"
}
catch
{
Write-Error -Message $_.Exception
throw $_.Exception
}
Write-Output "Done"
# Get new status (for testing/logging purpose only)
$NewAsSetting = Get-AzureRmAnalysisServicesServer -ResourceGroupName $ResourceGroupName -Name $AnalysisServerName
Write-Output "New tier: $($NewAsSetting.Sku.Name)"
using Set-AzureRmAnalysisServicesServer

There was a little bug in the PowerShell AzureRM.AnalysisServices module. It has been fixed in 0.4.0 (Thursday, June 08 2017)
Now the code finally works: http://microsoft-bitools.blogspot.com/2017/06/schedule-upscaledownscale-azure.html
