Looks like Verizon to Verizon texting broke in the recent update of Verizon Messenger. 3 of us went to the play store , Verizon messenger and uninstalled. This restored our previous version and it is now working again for the of us. I also went to the upper right corner in play store for Verizon Messenger , touched the 3 dots and unchecked auto update so this doesn't happen again until Verizon fixes this. One of us was on their way to a Verizon store and said the parking and store was crowded with many upset customers. Sour glad we sorted this out on our own.Hope this helps you and others.
