Already in one of my last posts I blogged about the ShellTileSchedule class. I love the simplicity of this class and still use it in my Shortcuts App you can get here. After a complete re-design of the App, I did a lot of testing and found an interesting bug.
My App did not refresh webcam images on phone, sms and mail live tiles.
I know the limitations of the ShellTileSchedule class and checked them again and again.
