The activity feed not updating in desk top
When I view the activity list on my iOS device, the unread items then do NOT show up on the desktop app. The only way I can see the new activities is to log into the Teams website version to see the activities that need attention. Once I click and view the activity in the feed, it then shows up in the desktop app, but any un-read activities don't show up in the desktop app until read in the browser setting.
I am having the same issue, but is beyond the activity feed. None of the posts in the channels or chat show up on the desktop app until I log into the website and view. This occurs every time the desktop program is off and then restarted. If the desktop program is up and running when a post is made, it works as expected.

I am experiencing this as well. This is not constant, it is sporadic and also affects alerts in channels as well. Sometimes I receive the notification from one user in a channel, but not from another user in the same channel.
