Please be aware that red dot notifications work differently depending on whether they are referring to chat messages or stream posts.
Users receive a red dot notification on the app icon for every post in the stream they have been subscribed for. If they receive a second or third notification about an additional post, the counter on the dot shows 2 or 3 respectively, and so on. This applies both for Android and iOS.
Chat 2.0 notifications
For Chats the notification behaviour differs between Androids and iOS.
- Android uses a red dot notification for chats 2.0 (but without counter)
- iOS does not use a red dot notification for chats 2.0
