Magic Keyboard 2 and Trackpad 2 are not connecting to MBP Bluetooth. If connected via lightening cable to Apple Thunderbolt Monitor they work fine but as soon as I unplug from the cable no longer useable. The devices are fully charged and am using OS10.11.6
MacBook Pro (Retina, 13-inch, Late 2013), OS X El Capitan (10.11.6)
