Bugs in msix version

Hi,

There's currently two bugs in the msix version of the desktop app. 

1. With every update, the icon is 'removed' from being shown in the taskbar. I pin it every time, but with next update, I have to do it all over again. It's annoying.
2. After update via Microsoft Store, the app does not start up again. I have to do that manually. The app should launch again after finishing the update.
