I'm am not receiving texts from a specific Verizon user, although she gets mine. She's on a Samsung S7 and I'm on Moto Z Force. We both can send and receive to/from others. When she texts me, her phone shows text as sent. We're both using native msg apps, have cleared out our texts to each other and have restarted our phones. We are currently communicating via email.
Is she using Verizon Messages+ application to send the messages? Are you? You should check out the Verizon Messages space for dozens of discussions regarding the current issues that application is creating for the users.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
