In iOS Meeting sdk, hosts/co-hosts in meetings are not able to distinguish a private message vs a public message on Chat window. This is new since the latest SDK v5.16.1.10538, while in Meeting SDKs v 5.4 and 5.7 private and public info on chat screen are available. please hep if we are missing something. i thinks this is SDK related issue. please check and resolved the issue ASAP.
