@praveen @rysiek For strict peer-to-peer connections both parties need to be online.The legacy group protocol allows offline-delivery using an explicitly untrusted (but cryptographically inefficient) service: https://docs.cwtch.im/security/components/cwtch/groupsThe newer managed groups are currently in beta, and allow the setup of trusted-groups i.e. allowing a member to run a server-bot which acts as a peer (so only the bot needs to be online for offline delivery to work): https://docs.cwtch.im/security/components/cwtch/hybrid-groups
