Have had several months of our SMS messages being blocked by Verizon. Anyone else having this issue? RC says no, but even with a brand new number, many of our messages to Verizon are blocked. Is happening with all of our staff. It's even happening to my own Verizon phone; so it's not that people are blocking us. It's a RC issue with Verizon. Happens when sending from the App and API. Probably the RC portal too but haven't tried.
