If you are having trouble accessing the iTunes Store and / or App store (on both iPhones / iPads and Macs) Well, you're not alone.
As we can see on Apple's "System Status" page, services are failing right now. According to the company, ?some users? are being affected and unable to make purchases at Ma's multimedia stores (iTunes, App and iBooks Stores).
According to MacRumors, there are also users complaining about Apple Music and other services, although Apple does not list any problems with them.
Developers are also being affected, more precisely with App Store Connect (where all applications are managed) and the TestFlight testing platform.
We'll see when all this returns to normal.
