Hello, I recently purchased a Pixel 8 device and loaded it with GrapheneOS. So far, the experience has been great, but it seems that I'm no longer receiving specific messages from those who appear to be using RCS and iMessage, based on my personal tests. I've tried enabling the Google Framework and Play services, loading up the Google Messaging to access RCS options (no success as it still says device unsupported), and looking into my carrier settings to see if there's anything I can do there, with no success. I use T-Mobile. Any advice or assistance? Thank you.
