RCS waiting for activation issue on iPhone and Xfinity Mobile

I'm having issues sending RCS messages to android customers from my iPhone 14 Pro Max.  Since the carrier is involved with RCS messaging on iPhone this may be some sort of carrier bug or maybe something in combination with a recent iOS update.

I noticed on the RCS Messaging tab in the Messages settings on my iPhone, it's basically stuck on "Waiting for Activation..."    Seems like my phone can't seem to connect with the RCS system.
