iPhone 13
My iPhone suddenly won't load apps anymore, information in settings doesn't load. iTunes store won't even load!
iPhone 13, iOS 16
if it was me then I would
try restarting the ios device Force restart iPhone - Apple Support and
check if it resolved it if it did not
then I would try Restore your iPhone, iPad, or iPod to factory settings - Apple Support - Apple Support if that did not resolve it then I would
contact apple about repair Contact - Official Apple Support
