PS: IDK if I managed to express it properly in the title. So excuse me if it sounded like something else. Don’t know how to say it better.
If you also are frustrated with the way WhatsApp notifications stack up in the Action Center, there’s some good news. The latest update to WhatsApp beta has introduced inline text for the notifications in the Action Center. So, instead of the message being shown next to the name, it will be shown below it. Just how it happens with the emails and texts and some other messaging apps.
