Starting on 6/17/18 between 1pm and 6pm I started having trouble texting my husband. He has an iPhone8 and I have a Google Pixel 2. We both got new phones about a month ago and I was able to text him fine. Then on June 17th after 6pm I texted him and it wouldn't go through. I discovered that I can only text him if I send a picture with it. What can I do to fix this?
