I'm new to Android and have a Motorola E second generation. Today I had a text exchange with someone (4 or 5 texts back and forth). Later I went to show the thread to someone else but only the last three texts were visible. I selected 'show more' but only one more message appeared. I can't work out how to see the rest of the thread - it seems to have disappeared. Any ideas why this happened or how I get to see the missing texts?
