Unable to Download Apps. Other apps (games and applications) keeps on crashing. Ipad becomes sluggish
i would like to know if this is some kind of bug after upgrading my unit to ios 9 and ios 9.0.2. i noticed that after such updates my unit becomes sluggish and some of the apps like samurai seige, fb messenger. photo vault were deleted one after the other. i have been trying to download it thru app store but i am always prompted as "Unable to Download App" ..... could not be installed at this time..
what should i do about this problem? i rebooted my unit for several times but the problem still exist... hope you can help me with this... thanks
