I have a fairly new Pixel 2 and use the standar Google Message app for text messages.
I can send and receive texts to anyone (individual or group) except 1 person!
I was able to send a long text to her on Dec. 14th and she replied, both successful.
Then on Dec. 20th I tried again and got the message "Not sent. Tap to try again."
Whether taping to try again or sending a new text, I get the same message and she doesn't receive the text.
She can continue to send me texts (and I receive them), no problem.
She has not blocked me in her Contacts, nor have I blocked her.
We are both on Verizon.
HELP!!! Suggestions?!?!??!
