Schedule shows up in previous week

if my app is running for a longer timespan (e.g. started on Friday, today is Monday) and I navigate to the scheduler page, the scheduler shows the last weeks timespan.
It should show the current week.
As a sideeffect, the method "NavigateTo" stops working.

HI Siggi, 
Thank you for contacting Syncfusion support. 
We have analyze the reported behavior “Schedule displays the previous week instead of current week”  and it works fine from our end, we have prepared a sample by placing schedule inside navigation page and navigate to schedule displays and it displays the current week as expected and we have tested the NavigateTo method and it works fine as expected. 
Sample: Schedule 
If the sample doesn’t meet your requirement kindly revert us by modifying the sample based on your scenario and replication procedure and furthermore details, which help us to analyze and resolve the reported issue.

maybe my description was not exact enough, so here are the steps to reproduce the error with your example:

1. Start your demo (UWP)
2. Press the button to show the scheduler
3. The scheduler is shown, with the current date (in weekview)
4. Navigate back to the start page
5. Set the date of your PC to one month in the future, simulating your app is running a full month, just showing the start page
6. Press the button to show the scheduler
7. The scheduler still shows the week from the original date, it should show the week from the new set date

hope that helps you to find that bug.

Hi siggi, 
Thank you for the update. 
We have analyzed the reported behavior “Schedule doesn’t move to the current date while update the date in windows on UWP” and you can achieve this in sample level by using NavigateTo method of Schedule, you can call this method while navigate to schedule with the required date time value and schedule will be navigated to the mentioned date. 
Sample: Schedule. 

We hope that this helps you, kindly revert us if you have any concern.

Thanks for your hint,
I tried to set the "NavigateTo" property in the code-behind of the SchedulerPage.
It works like in your sample, and can be taken as a workaround.

But it is not the optimal solution, here is what happens:

I use the MVVM pattern, so the VisibleDatesChangedCommand of the schedule is used.

1. Start app with current date, navigate to Scheduler (in week view)
2. VisibleDatesChangedCommand is called once with args.visibleDates.Count=7 with the current week dates, and the appointments are shown. Fine.
3. Navigate back to start page
4. Set date to one month in the future
5. Navigate to the scheduler
6. VisibleDatesChangedCommand is called with args.visibleDates.Count=7 with the new set date week dates. Great.
7. But then: VisibleDatesChangedCommand is called again with args.visibleDates.Count=7 with the OLD date week dates. Fail.
8. Now the "OnAppearing" of the SchedulerPage is called, with NavigateTo(Date.Time.Now)
9. And again, VisibleDatesChangedCommand is called with args.visibleDates.Count=7 with the new set date week dates.

As you can see, VisibleDatesChangedCommand is called three times with this workaround, and with every call the current appointments must be queried from database.

Please consider to treat this behavoir as a bug. The schedule should always use the current date when showing up, not the date it was started with the first time.

[EDIT] In addition, the NavigateTo doesn't work after that. Once called with a new date, the VisibleDatesChangedCommand is fired THREE times,
first time with the new dates, then with the dates from the very first showing of the Scheduler, third time with the dates last shown...........
