Apple Watch integration extremely buggy

Since the last few updates the Apple Watch integration is buggy. Oftentimes it will pause the activity for no reason, exit the app, or worse: will not let me finish an activity unless I restart the watch (and then Runtastic congratulates me on my super long workout). It used to be a pleasure to use, it enticed me to get a pro subscription but now I regret it.
