Thanks for these details, Rainson. We do not want to slow you down when it comes to messages. However, did you receive a message about upgrading your Verizon Message + client application? We sent out a message that if you are using an older version of Verizon Message + , you will receive a hard stop asking to have a newer version installed. This was a suggested fix, and you could try it. Here's a link if you wish to upgrade Verizon Message + client application on your Mac computer https://apps.apple.com/us/app/message/id885557198?mt=12 . Does this help?
