The Recent Message Notification bug in WhatsApp has now been fixed with the latest build 2.17.13 (beta), wherein the other notifications are now working properly instead of just showing the recent messages in an infinite loop. The new update now allows users to see all messages from one conversation (person or group) and not just the recent message, besides offering the Quick Reply option while responding to a new message from an earlier conversation.
Other noteworthy changes added to this update include correct notification expansion behaviour for conversations and multiple messages, notification fixes for Android Wear devices for improved readability and user-friendly contextual prompts while replying to messages.
Affected WhatsApp users are advised to download the latest beta version of WhatsApp (v2.17.13) by enrolling into the Play Store beta test program instead of awaiting its official rollout on the phone. Alternately, you can download the installation file manually via APK Mirror here.
