NotifyTime plus NotifyRepeatInterval do not work as expected

[fhintsch]

Describe the bug If I setup a notificationRequest with a Schedule.NotifyTime of let's say DateTime.Now.AddSeconds(5) and a Schedule.NotifyRepeatInterval of TimeSpan.FromMinutes(2), I will receive the first notification in 2 Minutes and not in 5 seconds.

To Reproduce

make a request like this:

                var nr3 = new NotificationRequest
                {
                    NotificationId = 123,
                    Title = "Wartung",
                    Description = "some description",
                    ReturningData = "test"
                    CategoryType = NotificationCategoryType.Alarm,
                    Schedule = {
                        NotifyTime = DateTime.Now.AddSeconds(5),
                        RepeatType = NotificationRepeat.TimeInterval,
#if DEBUG
                        NotifyRepeatInterval = TimeSpan.FromMinutes(2),
#else
                        NotifyRepeatInterval = TimeSpan.FromDays(1),
#endif
                    }
                };
                await LocalNotificationCenter.Current.Show(nr3);

Expected behavior I expected a first notification at Schedule.NotifyTime (in 5 seconds) and then repeated notifications every 2 minutes.

Platform (please complete the following information):

• OS: iOS 17.2
• Version 2.2.0

Smartphone (please complete the following information):

• Device: iPad (10th gen)

@fhintsch iOS dictates when to show notifications.

Does it work without the repeat time?

My Observation with Nuget 11.1.1, latest Maui - Android Version 14.

With RepeatType = NotificationRepeat.No, NotifyTime = DateTime.Now.AddSeconds(10),

If App is in front, the Local Notification properly shown after 10 ~ 11 Seconds If App is in background, the Local Notification shown after 13 ~ 14 Seconds If App is killed immediately after set, the Local Notification shown after 17 ~ 20 Seconds

No other front Apps are running.

Please check. Thanks
