[Problem/Question]
My app doesn’t receive the events like Typing, onNewMessage and others even though the app is foreground and inside the chat screen screen. All listeners are setup and active. Many times happen this.
SDK Version: com.sendbird.sdk:sendbird-chat:4.19.1
I notificted the following statement in console:
Discard the command[ReadEventCommand] because app is in background

To reproduce this issue, You just launch the app and send the message from other user and you will not receive any new message until you refresh or jump to his chat window.
