If I use the restart in the reset settings, in the sky q box will lose the sky sports plus app

If you use the "Restart" option in the reset settings on your Sky Q box, it typically doesn't delete any apps, including the Sky Sports app. A restart generally refreshes the system and can resolve minor issues without affecting your installed applications or settings. However, if you're considering a "Factory Reset," that would erase all downloaded apps and settings, and you would need to reinstall any apps, including the Sky Sports app. Always ensure to back up any important settings or information if you're unsure about what a particular reset option entails. If in doubt, you can consult Sky's official support for specific instructions related to your situation.
