Ask for a verification after a period of time

In my Xamarin Forms app, I want to see if the user is still active. I have a form in my app that shows a random code and asks the user to enter it. How can I show this form every, let's say 10 minutes? This should work if the screen is off and the app is minimized.

Service is run once... then never again

I created my app as I wanted a widget to display some status text on my home screen. Upon adding the widget to to home screen it updates to never update again... As a workaround I've added click event to the widget, so the click triggers the update of the widget - but that also dies, in order to fix that I have to open the application, go to my home screen en tap the widget and it will update. After a couple of minutes it does not respond to clicks again. And it never updates the widget by the set interval (updatePeriodMillis).
I've not put my app in the list of application that the OS will sleep.
Anyone have a clue?

Go to the File menu and make sure that "Save Data With Report" is turned off

Event time displaying in GMT after clicking "more details"

My default Google Calendar timezone is "(GMT-05:00) Eastern Time". The event time displays correctly on the calendar and in the initial pop-up window, but if a viewer who is NOT logged in to Google Calendar clicks the "more details>>" link in the pop-up window, the next screen displays the time in "GMT (no daylight saving)". So, for example, an event that displayed as "8:45am Eastern" on the calendar and in the pop-up now displays as "12:45pm GMT (no daylight saving)" on this "more details" page. Could you please let me know to resolve this.
Its a simple fix for this issue and it is that we need to append &ctz=America/Chicago to #URL# and now logged-out users see the correct timezone.
