My fiance has had her Motorola X Pure for about almost a year, (She got it at launch). We both have unlimited data so she paid full price for it. Lately more and more of my texts and hers have not been sending, or MMS photo attachments. I've checked her service and that seems to be fine. She's using Textra which we both love. We don't want to switch to something like Hangouts etc just yet, what can I check to ensure she's getting her texts properly? I've read maybe flushing the cache from the Android Boot menu.
