Text notification issue

Hello,

Has this ever happened to anyone else? It's been happening to me sporadically for months. I'm updated on the newest iOS version, I have an iPhone 6. Sometimes I will never receive a notification for text messages. Only for text messages. Today it happened again. I text someone that I don't normally text and didn't get a response right away. I didn't look at my phone ( or get any type of notification for that matter) for 3 hours until I randomly decided to look at my messages app. I look and there's 4 different messages waiting for me. Nothing on my home screen, nothing in my Notification Center ...so strange. It's fixed by holding power and home and restarting the phone but I never know when it's happening. Has this happened to anyone and is there a permanent fix? I don't want to complete start fresh because I don't want to lose my watch data. Also this only happens when I'm not wearing my watch.

 

I would loose my watch stats right?

 

I mean.. I guess it could be the case. It does only happen when I take the watch off

 

Interesting.. Ill have to double check when it happens
