With the new feature, WhatsApp has become even more like Telegram
WhatsApp developers have borrowed another feature from Telegram. With the latest update, messenger users now have the ability to pin messages in chats and personal correspondence.
Journalists of the online publication WABetaInfo were the first to pay attention to the innovation. The function of pinning messages was added by the messenger developers in version 2.23.13.11. They can be fixed for one month, one week, and one day. To view a pinned message in its entirety, just touch it with your finger. The new feature will allow WhatsApp users to avoid missing important messages.
Currently, the function of pinning messages is at the final stage of testing. The WhatsApp app with it will appear in app stores in the near future.
