Terrible syncing between Watch and iPhone

Seriously, Nike... Get it together! I used to LOVE this app before the big overhaul. It used to be a little bit slow in syncing between my Apple Watch and iPhone 6, but now it doesnt even work. If I start a run on my watch, a run is NOT started on my iPhone. And if I start a run on my iPhone, a run is NOT started on my watch. The only time there is somewhat of a sync at all is when I start a run on both Watch and iPhone independently. Unfortunately when I do this, my iPhone has a tendency to auto-start, stop, start, stop a run over and over again... And the worst part... Both devices register distances separately. So yesterday I went on a run which is typically 9KM... My iPhone registered the usual 9KM as an indoor run and my Watch registered 8KM as an outdoor run. Please please PLEASE fix this asap, otherwise Im going to be forced to switch apps.
