    Important: Always check the developer’s changelog before updating BlueStacks. A major BlueStacks update (e.g., 5.21) might temporarily break compatibility until a new BS Tweaker patch is released.

    Keep a close eye on community forums for patches if you auto-update BlueStacks. Better yet—disable auto-updates from within BS Tweaker’s settings.
