I’ve used Pixel phones since they were called Nexus, and it was fun for a minute, but I had too many unexplained issues with RCS and eventually just disabled it. Nowadays, the people I text with most frequently are on Signal. For a variety of reasons, I’ve shifted to giving people my Google Voice number rather than my “real” number, and Voice doesn’t support RCS. So even if I wanted to use RCS, it’s not even an option for most conversations.
