desktop app not showing message indicator (sound and desktop notification work)

Description:

We have upgraded our rocketchat from version 2.x to 4.8.2 (with migration over the versions). Desktop notifications are working, sound for new notification is playing. But the number indicator at the left side for channels is not showing up / or disappearing when the massage is read. It is needed to reload to see the changes. Also applies for status (online, away ..)

Steps to reproduce:

1. Get Notification from user
2. Sound is played, Desktop notification overlay is shown
3. Switch to Rockatchat app, no indicator update for channels

Expected behavior:

Sidebar should update status of users and new massage indicators and remove old indicators

Actual behavior:

Sidebar is not updating status of users and new massage indicators and remove old indicators
