If you’re using older versions of the apps on iOS and Android that don’t support the feature, you’ll be kicked from the meeting if the hosts turn on the locks; if they’re turned on ahead of the meeting and you’re on one of those older apps, you won’t be able to join the meeting at all. Google says that turning off the locks will let people using older apps participate in a meeting.
All Google Workspace customers will have access to the feature, which began rolling out for users on the Rapid Release tracks on Thursday. It will start rolling out for those on the Scheduled Release track on November 1st.
