  <p>my viewmodel:</p>
  <pre><code>public ObservableCollection&lt;PlanToFirestoreModel&gt; Plans { get; set; }
      
           public PlansViewModel() {
               firestoreService = DependencyService.Get&lt;IFirestoreService&gt;();

               FillData();
           }
      
           public async void FillData()
           {
               var tempPlans = await firestoreService.GetFlightPlansByUid(auth.GetUserInfoAsync().Id);
               foreach (var plan in tempPlans)
               {
                   Plans.Add(plan);
               }
           }
  </code></pre>
  <p>and my Model itself:</p>
  <pre><code>public class PlanToFirestoreModel : BasePlanModel
       {
           public string fromICAO { get; set; }
           public string toICAO { get; set; }
           public string fromName { get; set; }
           public string toName { get; set; }
           public int id { get; set; }
           public string userId { get; set; }
           public string aircraft { get; set; }
           public string deptCountry { get; set; }
           public string arrCountry { get; set; }
           public double fuelUsed { get; set; }
           public string flightNumber { get; set; }
           public double distance { get; set; }
           public string altitude { get; set; }
           public string createdAt { get; set; }
           public double deptLon { get; set; }
           public double deptLat { get; set; }
           public double arrLon { get; set; }
           public double arrLat { get; set; }
       }
  </code></pre>
  <p>The XAML page can find the Plans ObservableCollection itself but not the properties that are supposed to be in the list like &quot;fromICAO&quot; and &quot;toICAO&quot;
  The label within the datatemplate can also only find Plans but not the properties within.
  What am I doing wrong?</p>
