The long-awaited feature is coming
WhatsApp is currently only available on one device at a time-at least in the form of an app. This is likely to change soon, as the service is currently using multi-device support.
WhatsApp is currently testing some new features that will be available to us shortly. In addition to the message's self-destruction mode, the Messenger service obviously can also run on multiple device support. This will report on Wabetainfo, a website specializing in WhatsApp. Therefore, WhatsApp can be used in parallel on multiple devices in the future.
Currently, it can only be implemented to a limited extent through WhatsApp Web, but cannot be used on two smartphones or tablets through regular applications. Features that many users have long missed. According to Wabetainfo, multi-device support will be tested in the latest WhatsApp beta for Android 2.20.110, but has not yet been activated. In the tweet, the website showed instructions for new features.
If one of your contacts installs Messenger on another device in the future, you will receive a notification because the encryption key in the application has changed. When the new features will be introduced is unclear. It can be assumed that the feature is first activated in WhatsApp beta and is checked by testers for errors until it is finally activated for all users.
By the way: WhatsApp has started to introduce the first restriction in Messenger due to the corona crisis. To ensure your safety in the current situation, we recommend installing a backup Messenger in case WhatsApp is overloaded.
