Messages in Channels no longer appearing

[Poitier]

We've been using the channel features for a few years to communicate with our agents. Today, no one is seeing messages or replies posted in the channel by other members or admins. I updated Zoom to version 6.2.6 and asked agents to do the same but it didn't fix the issue. I've also checked the settings for the channel and nothing is out of place.
Private chats are working, but using the private channel is critical for us.
