RCS Chats Not being delivered to iPhones

I got a new phone (Moto Razr 2025) and my RCS messages aren't getting delivered to iPhones.  Google Messages is saying I'm in RCS mode, I can see when the other person is typing, RCS is connected to my number, the message won't send.  I have to send it as a text to get it to send.  Seems to only be an issue with me sending to iPhones.  I've done all the usual trouble-shooting: updating messages, restarting the phone, disconnecting and reconnecting to RCS, turning off RCS in my old phone...but nothing is getting it to work. Any suggestions?
