Pixel XL
I have an issue where if I'm using the mobile app and I'm actively engaged in a chat or a team thread, any time a user posts or replies it doesn't populate in the thread I'm staring at. It pops up a notification along with sounds an audible notification. If I click on the pop up it refreshes the thread and shows the reply and/or post.
That's super obnoxious and I can't locate a tweak in the settings to fix this. Is this a bug? User error? I really do not enjoy the mobile app strictly because of this issue. If I'm actively engaged in a thread and someone posts something, it should just populate in the thread and not sound my notifications and require a refresh.
Your help and attention to this would be greatly appreciated.

This sounds like a bug. On your mobile device, please go to ‘Settings > Report an Issue’ on your Teams app to send us logs.
