For the last few days my Moto X keeps giving me the notification that a text message I sent was not sent - but when I touch to see the message in question it just takes me to the main messaging screen showing all the different threads. When it first showed up I had just sent two different text messages to two different people - and both replied to the message. I've received this notification before, but when I would press the alert it would show me the message that wasn't sent for one reason or another and it would go away once I acknowledged it. If I dismiss it, it will come back in the next 30-60 seconds, or the next time I go into the messaging app, and if I turn off notifications it doesn't tell me when I receive a text. This is the default messaging app. Has anyone else experienced this, or does anyone have any suggestions? I'd rather not delete every thread since I have a number of work related conversations and having them as a reference is a good thing.
