@Mes_Android. Welcome to the Sendbird Community. I will try to answer your questions below.
Q: If a user sends a message to another user, SendBird push notification for the first message only, and next messages no notifications are sent. Sendbird won’t send another notification even the receiver has canceled the notification ( by swipe ) the only way to get notifications again is by asking the receiver to open chat again.
A: This is not the expected behaviour. In most conditions Sendbird will send a push notification for all messages. However, this depends on your Sendbird Dashboard push notification settings (explained below) and the online status of the receiving user.
Q: Is there any assistance from the backend dev so push all notifications whether app in the background or foreground?
A: In your Sendbird Dashboard there is an option to send push notifications regardless of the device being in the background or foreground. Sendbird Dashboard → Settings → Notifications → “Send as long as one device is offline”
If you setSend as long as one device is offlineto be on the current Android SDK version is receiving notifications all the time, regardless of being in the foreground or background. Please let me know if you need to be able to see notifications if the app is in the foreground.
Q: Can backend dev assist in sending multiple notifications?
A: As mentioned Sendbird does send mulitple push notifications.
