I have a Pixel 3. I try to avoid using SMS and instead use Signal whenever possible. When I do use SMS (the Messages app), I don't want "RCS chats" to be enabled. But nearly every time I open the Messages app, I'm prompted with a popup where the "Agree" button is very prominent.
I do not want to agree to use RCS chats. I want my choice (when I click "Use Messages without RCS chats") to be permanent.
How can I fix this?
