(iOS/Swift) Using SBSMChannelCollectionDelegate when I receive a new message it updated twice the channel when the app is on foreground, the first time with the correct data, correct number of unread messages, etc. the second time it updates it has 0 new messages, but moving to background or closing…

pending message id 0 is normal, and it doesn’t get affected by sending status. You have to use the object from callback.

am I writing this correctly? - (void)setPendingMessage:(SBDBaseMessage *)message { if (message) { [self.collection appendMessage:message]; } } - (void)setSentMessage:(SBDBaseMessage *)message { if (message) { [self.collection updateMessage:message]; } } [self.coll…

@Woo , the issue got fixed in some devices, some didn’t experience the issue for a while but then it came back in. https://share.getcloudapp.com/Wnub7b6J

Are you sure both simulators running on latest SDK?

I am not using simulators, this is from a build sent to my project manager to test the issue, it worked for around an hour then the issue started happening again.

Ok, it would be helpful if you can tell me whether it consistently happens or works when you restart your app. Did you install latest SDK on both side? and would you try to comment out markAsRead and tell me if this happens?

the issue is behaving the same way, mark as read is commented out, although the chat view controller would need to be open for it to be called… when the app is active, issue happens, when sending the app to aground and coming back in data is correct, or closing and opening the app, has correct data,…

So even though markAsRead is commented out, still happening? Yes I know markAsRead is needed, I just want to make check if it causes the issue. And you didn’t answer my question, could you confirm both ends use latest SDK version?

Oh I see the same result when I enter and exit and re-enter again… I will dig again. One last thing, I observed same issue when UserA (chat view) sends a message to UserB (channel list view) UserB enter to chat view and send a message UserB goes back to channel list view UserA sends a message agai…

And if you made your project from the sample, there’s memory leak that chat view is not released properly -> which causes to call markAsRead when other user sends a message. I’ve updated sample app (fixed memory leak), and I do not see the problem anymore. Please check the sample app :slight_smile: …
