    I’m always skeptical of tips that are destructive in nature. Why do I have to delete and reinstall when I can use an app to do it without deletion? Makes more sense to me.

    • Yeah. i agree with you, uninstall and reinstall again and again, that’s boring and time wasting.

    Hope Apple can provide an option to clear documents and data in the future.
