The latest beta update of WhatsApp is rolling out the new limit of participants for group calls, according to WABetaInfo. Until now, group calls were limited to a maximum of four participants but the latest beta update will let users add up to eight participants in a group voice or video call. Earlier this month, the firm made some changes to how the call button functions in groups, permitting users to simply start a call if there are less than four participants.
In order to have the upgraded participants feature, iOS users need to install the 220.127.116.11 beta update from TestFlight while Android users can install 2.20.133 beta version from the Play Store. If any of the call participants aren't on the same version, they won't be added to the group call.
Now, when you click on the call button in a group, WhatsApp will ask you which contacts you wish to call if there are more than four participants in the group. Otherwise, if there are four members or less in the group, all participants will be added to the call.
