When debugging the applications try to use the Windows version as much as possible.
There are cases when you can't use the Windows version for debugging and have to debug on the device. For example to test device motion. You can use Visual Studio for that purpose, but beware:
Ctrl + Click on any element on the page to launch the inspection window. Then from the drop-down list at the top right corner, select a device to see the application updated for that device size and styles. Make sure to download the Android and iOS fonts for Windows.
