Texting issue topic

I just got my LG G watch for Xmas, I down loaded and installed the Android ware app on my Samsung Galaxy S5, paired it up with the watch. The watch updated itself to 5.0.1. I notifications are sporadic, some times I get a facebook notification, then nothing. people don't get my texts even though it goes to the Galaxy and says it sent, I get text notifications. I have sent to both iPhones and Android phones, anyone have an Idea. I even returned the watch for a replacement, same issue.
