```powershell
Get-AzSubscription -SubscriptionId $peersubid | Set-AzContext
$ckt2 = Get-AzExpressRouteCircuit -name $PeerExpressRoute -ResourceGroupName $PeerERResourceGroup
If($ckt2){$AuthKey = ($ckt2.Authorizations | Where-Object {$_.Name -eq $AuthKeyName}).AuthorizationKey}
Get-AzSubscription -SubscriptionId $subid | Set-AzContext
$ckt1 = Get-AzExpressRouteCircuit -name $ERCircuitName -ResourceGroupName $ERResourceGroup
$ckt2privpeer = ($ckt2.peerings | Where-Object {$_.Name -eq "AzurePrivatePeering"})
Add-AzExpressRouteCircuitConnectionConfig `
-Name $GRName `
-ExpressRouteCircuit $ckt1 `
-PeerExpressRouteCircuitPeering $ckt2privpeer.id `
-AddressPrefix $GRAddressPrefix `

Start by rerunning the listed Get-AzSubscription, Get-AzExpressRouteCircuit, Add-AzExpressRouteCircuitConnectionConfig, and Set-AzExpressRouteCircuit sequence, then compare it with the working Azure CLI method. Trace why Set-AzExpressRouteCircuit returns the unmodified circuit without an error; done means the PowerShell sequence establishes Global Reach and persists the connection configuration.
