How to temporarily disable button after click in Xamarin Forms even when navigating through the app?

Question

I am making a voting app and I want the user to be allowed to vote just one time/day. I have a main page and on this page, multiple buttons navigating to different pages (where the user can vote).On the voting "page" I have a button that when is pressed, it uploads the vote into a database, and after it is disabled for some time. However, if I go back and forth (voting page -> main page -> voting page) the button is once again enabled. How can I solve this, so wherever I navigate the button will remain disabled? I write down the code that I use to disable the button on the voting page, but as I said, whenever I leave the page the button will be enabled again.

public void ImageButton_Clicked(object sender, EventArgs e)
       {
           Timer aTimer = new Timer();
               myButton.IsEnabled = false;    
               aTimer.Interval = 5000; //ms
               aTimer.Enabled = true;
               aTimer.Elapsed += ATimer_Elapsed;

       }

       public void ATimer_Elapsed(object sender, ElapsedEventArgs e)
       {
           Device.BeginInvokeOnMainThread(() => { myButton.IsEnabled = true; });
       } 

The Xaml definition of the button.

<ImageButton 
x:Name="myButton"
Clicked="ImageButton_Clicked" >

I guess that you want to store data when leaving page using Navigation, if yes, I suggest you can use Xamarin.Essentials: Preferences to save current user data.

For MainPage:

 private void btn1_Clicked(object sender, EventArgs e)
    {
        Navigation.PushAsync(new Page15());
    }

For VotePage:

 public partial class Page15 : ContentPage
{  
    public DateTime dt;
    public Page15()
    {
        InitializeComponent();        
        DateTime currentdate = DateTime.Now;

        bool haskey = Preferences.ContainsKey("user1");
        if(haskey)
        {
            string date = Preferences.Get("user1", "");
            if (date != null)
            {
                dt = Convert.ToDateTime(date);
                TimeSpan timediff = currentdate - dt;

                if(timediff.Seconds<10)
                {
                    btnvote.IsEnabled = false;
                }
            }             
        }           
    }

    private void btnvote_Clicked(object sender, EventArgs e)
    {          
        dt = DateTime.Now;

        //save count into database or local
        btnvote.IsEnabled = false;

    }

    protected override void OnDisappearing()
    {
        base.OnDisappearing();
        string clickdate = dt.ToString();
        Preferences.Set("user1", clickdate);
    }
}

In my code, I disable Button within 10 seconds of voting, you can use timediff.Days;timediff.Minutes to change datetime difference.
