WhatsApp is working on a new update that will let you sync chats across mobile devices. The update will roll out through the Google Play Beta Program, with version 2.22.15.13 of WhatsApp, as reported by WABetaInfo.

According to WABetaInfo, when logging into a secondary mobile device, it may take a while for older chats to show up as they're in the process of being securely synced. To that end, WhatsApp is working on adding the same system message as seen on the WhatsApp Web/Desktop app. On the Desktop or Web app, when older messages aren't available, you're shown that the old messages are still being synced. The same message will now show with the new feature on your secondary mobile device. There is however, no fixed release date for the new feature as it is still under development.

There were previously reports that the app was working on the ability to link a second mobile device to a WhatsApp account without requiring an active internet connection of the primary device. This feature, dubbed companion mode, is also yet to roll out. Once it's out, users will be able to send messages through the second mobile device as well.

Additionally, WhatsApp is also working on giving users the ability to completely hide their online status. The new feature will ensure that only selected contacts will be able to see a user's online status.
