I'm using a Pixel 7 Pro running Android 15. When I text with a person using iOS 18 on an iPhone I get the "Sent" circle and check mark and the "Delivered" circle and check mark, but the circles don't turn blue to indicate "Read" once the recipient has read the message (like they do on Android-to-Android RCS). Is this a setting I need to change on my end or is it an iOS problem. This happens with multiple iPhone users.
