Multi-device support from WhatsApp: Here is what you cannot perform on connected devices
WhatsApp's multi-device functionality will be available to beta users soon. The multi-device beta is an opt-in program that allows you to try out a new version of WhatsApp for Web, Desktop, and Portal before it is released to the public. WhatsApp beta users will be able to connect up to four devices to their account, including browsers and other devices, but not another phone.
Users can use WhatsApp on these linked devices even if their primary phone does not have an active internet connection. The linked devices though will be logged out automatically if the main device hasn't connected for more than 14 days.
WhatsApp and WhatsApp Business app beta users using the newest version of WhatsApp beta on Android and iPhone, as well as WhatsApp and WhatsApp Business app users in select countries, can participate in the multi-device beta. WhatsApp announced in a post that the multi-device beta will be rolled out globally.
What are the limitations of linked devices?
Despite the capabilities of the feature, there is a long list of WhatsApp features that you cannot use on the linked devices. Viewing live locations on partner devices, pinning messages, joining, viewing, and resetting group invites via WhatsApp Web and Desktop, and more are among the features included.
Users will also be unable to call someone directly from a linked device if they are using an older version of WhatsApp on their phone. It's also not possible to make calls from Portal or WhatsApp Desktop to linked devices that aren't part of the multi-device beta.
Other WhatsApp accounts on the portal, on the other hand, will not work unless they have also signed up for the multi-device beta. WhatsApp Business users can't change their business name or labels from the web or desktop version of WhatsApp.
