I really want to use this app... but it CONSTANTLY fails to send and receive messages. I confirm that I have data connection... but Messages often says "connecting" and I can see messages getting received by other people so I know the problem is with my client. I've opened feedback and invited Google to contact me for debugging help (I work in tech). Google.. you gotta get this working if you want a good of convincing Apple to interoperable with RCS. right now... is warm people away!
