RCS Read Receipts Vanish in Google Messages, Leaving Users in the Dark

In the past week, users of Google Messages have experienced issues with RCS read receipts not being displayed properly in some conversations. The delivery status indicators show messages being sent and delivered, but do not confirm if they have been read, which is a persistent problem affecting both the stable and beta versions of the app. This issue impacts various conversation types and design styles, suggesting it could be related to server-side functionality rather than an application bug. Despite no changes made to settings, unchecking and rechecking the option for sending read receipts does not resolve the problem. The issue appears widespread among users.
