Cannot add app. Getting error when adding the apps/desktop to favorites

1. Replace the following section in the C:\inetpub\wwwroot\Citrix\storenameWeb\web.config file for affected store with the correct store name. (where storename is the name of the effected store)
   • Old state entry:
   • <subscriptionsStoreClient enabled="true">
   • <clientEndpoint uri="net.pipe://localhost/Citrix/Subscriptions/1__Citrix_Marketing"
2. Replace with correct store name:
   • <subscriptionsStoreClient enabled="true">
   • <clientEndpoint uri="net.pipe://localhost/Citrix/Subscriptions/1__Citrix_Store"
3. After this restart subscription service on the storefront server. propagated changes and we were able to add favourites.
