OnSfSchedulePropertiesChanged throws exception on UWP

[Emil]

I am getting exception below for some desktop devices in UWP. it looks like that it is related with masterdetail page, if I have page with masterdetail and one of the page implements sfschedule on a page and when I navigate away from the page where sfschedule is it throws this exception. I think that i had either another incident or thread regarding this.

Stacktrace

We have logged an issue report on this. We will fix the issue and include the fix in our upcoming volume 1 SP2 release which is expected to be available by end of month April 2018.
