Following threads can be very frustrating and confusing. Notifications are also not always helpful.

Good app

Better and easy to communicate

Annoying notification bubbles

It constantly says 1 notification exists despite being up to date on everything. Why do I have to click through “unread” tabs that are entirely empty to get rid of the bubble?!

Workspace re-ordering is broken on iOS

When dragging in workspace position on iOS, to a new position, that location is not saved and it revert back to the old position. This happens on some work spaces and not other others.

Business Essential

Slack bot has changed the game when it comes to communicating with my colleagues. Fast reviews and concise responses make Slack a better place.
