Sendbird UI Kit v3 channel not displaying data

I’m trying to use the SBUGroupChannelListViewController and whenever I go into a channel, it is displaying no data in iOS using the UIKit.

I went through the basic “Send your first message” workflow, and it is still not displaying the data.

I call initialize:
SendbirdUI.initialize(applicationId: applicationId) {
} completionHandler: { error in

I initialize the user:
SBUGlobals.currentUser = SBUUser(userId: user.userId)
SBUGlobals.accessToken = user.accessToken

And then I present the channel list view controller:

The data gets displayed correctly for the channel list, but not each individual channel. Has anyone seen this issue before?
