App lists only one account

[RoSchmi]

When using the App only one of my Storage Accounts is listed.
In the code in AzureManagementHelper.cs
StorageManagementClient client = new StorageManagementClient(cred, httpClient);
var response = await client.StorageAccounts.ListAsync();

response contains only one account although there are more than one.
Is this a bug in the library?
Kind regards
