Please forward this bug report to the development team of Candy Crush Saga for Windows 10:
Inside the Candy Crush Saga Windows 10 app, there is a "play Candy Crush Saga" button to switch to the other game. Clicking this button, however, opens up the Google Play Store, instead of the Windows Store. This happens even if you have Candy Crush Saga installed on your Windows 10 PC - clicking the button "Play Candy Crush Saga" still opens the Google Play store for some strange reason. Please fix!
