Lightswitch HTML Sharepoint App: Access Control Methods

Question

I have a Lightswitch HTML SharePoint App. Which is working well.
I have implemented user access security on the entities using SharePoint groups.
partial void UserAccessGroups_CanUpdate(ref bool result)
result = false;
var clientContext = Application.SharePoint.GetHostWebClientContext();
Microsoft.SharePoint.Client.Web web = clientContext.Web;
Microsoft.SharePoint.Client.GroupCollection UserGroups = web.CurrentUser.Groups;
clientContext.Load<Microsoft.SharePoint.Client.GroupCollection>(UserGroups);
clientContext.ExecuteQuery();
foreach (var item in UserGroups)
var permission = "UserAccessGroupAdmin";
if (item.Title == permission)
result = true;
break;
This works fine when I am debugging the application and it is running on localhost.
However when I publish theapp and it is running in an Azure site it doesn't work and I am un able to edit the entitiy.
I have set up the SharePoint Group on the site that is running the appp and assigned the user to the group.
Has anyone else had a similar experience or have any suggestions.
Thank you,
Andrew

I have SharePoint permissions in that example and I tested it in production and it definitely works.
bool isMemberOfVacationApprovers = false;
var clientContext = this.Application.SharePoint.GetHostWebClientContext();
//Load the properties for the web object.
Microsoft.SharePoint.Client.Web web = clientContext.Web;
// Get the current web
clientContext.Load(web);
clientContext.ExecuteQuery();
// Groups for current User
Microsoft.SharePoint.Client.GroupCollection UserGroups = web.CurrentUser.Groups;
clientContext.Load<Microsoft.SharePoint.Client.GroupCollection>(UserGroups);
clientContext.ExecuteQuery();
foreach (var item in UserGroups)
if (item.Title == "Vacation Approvers")
isMemberOfVacationApprovers = true;
if (!isMemberOfVacationApprovers)
results.AddEntityError
("Only members of Vacation Approvers can edit this record.");
