Get-AzVm does not return all UserAssignedIdentities

[EyeSeeKirk]

Description

We have over 100 user-assigned managed identities on each of our virtual machines. We can see them in the portal.

However, when running the following PowerShell commands in the Azure Cloud Shell,

 $vm = Get-AzVM -ResourceGroupName $rg -Name $vmName     
 $assigned = $vm.Identity.UserAssignedIdentities.Keys          
 $assigned.Count   

We only get 70 identities.

Issue script & Debug output

$vm = Get-AzVM -ResourceGroupName $rg -Name $vmName     
$assigned = $vm.Identity.UserAssignedIdentities.Keys          
$assigned.Count
