    Hi @s44,
    A bit different approach - your various message requirements made this more complex 
    If(
       "/" in Self.Text;
       With(
      {dateParts: Split(Self.Text; "/")};
      With(
         {
            day: Value(First(dateParts).Value);
            month: Value(Index(dateParts; 2).Value);
            year: Value(Last(dateParts).Value);
            enteredDate: DateValue(Self.Text; "fr-FR");
            minValidDate: DateAdd(Today(); 3; TimeUnit.Months);
            maxValidDate: DateAdd(Today(); 3; TimeUnit.Years)
         };
         With(
            {
               _ErrorDates: 
               month = 1 && day > 31 || 
               month = 2 && day > If(Mod(year; 4) = 0; 29; 28) || 
               month = 3 && day > 31 || 
               month = 4 && day > 30 || 
               month = 5 && day > 31 || 
               month = 6 && day > 30 || 
               month = 7 && day > 31 || 
               month = 8 && day > 31 || 
               month = 9 && day > 30 || 
               month = 10 && day > 31 || 
               month = 11 && day > 30 || 
               month = 12 && day > 31;
               _ErrorFormat: !IsMatch(Self.Text; "^\d{2}/\d{2}/\d{4}$");
               _ErrorMax: enteredDate > maxValidDate;
               _ErrorMin: enteredDate < minValidDate
            };
            With(
               {_Error: _ErrorDates || _ErrorFormat || _ErrorMax || _ErrorMin};
               If(
                  _Error;
                  Notify(
                     If(
                        _ErrorDates;
                        "Date invalide.";
                        _ErrorFormat;
                        "Date invalide. Veuillez entrer une date au format JJ/MM/AAAA.";
                        _ErrorMax;
                        "La date doit être inférieure à 3 ans.";
                        _ErrorMin;
                        "La date doit être supérieure à 3 mois."
                     );
                     NotificationType.Error
                  );;
                  Reset(Self)
               )
            )
         )

    OK - I do not think it is possible (without a lot of brain frying) to cover every possibility of what a user might enter. Also if you want to change numbers to xx/xx/xxxx "on the fly", you will need to set the Default of your text box to (in the example) varDate, so you may need to clear this before the user enters the next date, My best effort below 
    If(
   Len(Self.Text) > 0;
   If(
      !("/" in Self.Text) && Len(Self.Text) = 8 && IsNumeric(Self.Text);
      UpdateContext({varDate: Left(Self.Text; 2) & "/" & Mid(Self.Text; 3; 2) & "/" & Right(Self.Text; 4)});;
      Reset(Self);
      UpdateContext({varDate: Self.Text})
   );;
   With(
      {dateParts: Split(varDate; "/")};
      With(
         {
            day: Value(First(dateParts).Value);
            month: Value(Index(dateParts; 2).Value);
            year: Value(Last(dateParts).Value);
            enteredDate: DateValue(varDate; "fr-FR");
            minValidDate: DateAdd(Today(); 3; TimeUnit.Months);
            maxValidDate: DateAdd(Today(); 3; TimeUnit.Years)
         };
         With(
            {
               _ErrorDates: 
               month = 1 && day > 31 || 
               month = 2 && day > If(Mod(year; 4) = 0; 29; 28) || 
               month = 3 && day > 31 || 
               month = 4 && day > 30 || 
               month = 5 && day > 31 || 
               month = 6 && day > 30 || 
               month = 7 && day > 31 || 
               month = 8 && day > 31 || 
               month = 9 && day > 30 || 
               month = 10 && day > 31 || 
               month = 11 && day > 30 || 
               month = 12 && day > 31;
               _ErrorFormat: !IsMatch(varDate; "^\d{2}/\d{2}/\d{4}$");
               _ErrorMax: enteredDate > maxValidDate;
               _ErrorMin: enteredDate < minValidDate
            };
            With(
               {_Error: _ErrorDates || _ErrorFormat || _ErrorMax || _ErrorMin};
               If(
                  _Error;
                  Notify(
                     If(
                        _ErrorDates;
