Several users have reported the impossibility, in the last hours, to download and update the applications previously installed on the iPhone via the App Store because of a malfunction that is likely at this time hitting the iTunes Store.
The mistake that many are receiving is not therefore attributable to possible malfunction of their network or ID associated with Apple, but these just temporary problems that appear to be on Apple’s servers. Suggest, therefore, not particularly alarmed but to wait patiently for the engineers to correct these errors and restore the optimal functioning of the App Store and the iTunes Store.
Nothing very worrying fact.
