MLB Not Working on iPad, iPhone, iPod, Android, Amazon Fire TV etc.

Please note that we don't support MLB on iPads, iPhones, iPods, Android devices including Amazon Fire TV, Fire Sticks, and Nvidia Shield. The reason is that this version of the MLB app uses location services on the devices, which can't be bypassed via the network. On some devices GPS info is used on other devices the Google Play Location Service API is used. Either way, none of these can be bypassed by VPN or DNS. 

So while you can unblock MLB blackouts on a long-range of devices with Unlocator the above devices are not supported for MLB blackouts.
