WhatsApp is reportedly rolling out a new update for Android smartphones that offers the ability to create communities. The feature is said to be available to a limited number of beta testers at the moment.
WABetaInfo reports that the Communities tab is showing up for certain users who updated to WhatsApp beta for Android v188.8.131.52. You can try force closing the app and relaunching it to see if that enables Communities for your account if you are already running the latest beta. In case you are among the lucky users to have access to the feature, you should see the Communities tab instead of the Camera tab on the main WhatsApp screen. You can head over to the tab and start by creating a Community where you can add up to 10 groups with support for up to 512 participants.
A community member can decide which sub-group to join based on their interest. They can also exit the sub-group whenever they want without leaving the community itself. The messaging service is also working on hiding the numbers of sub-group members from other participants for privacy reasons. However, this feature is not active in the current Communities version. WhatsApp will automatically create a new announcement group when you create a community. Admins can use this group to make announcements and send messages visible to all community and sub-group members. Additionally, admins can disable the community altogether if they wish to.
