Difficult iPhone experience

Generally a great product for internal communications but the app is clunky.
1. When I receive a message I touch the push notification and it takes me to the last part of the conversation I viewed in app. Not the message I just received. So I have to scroll through any conversation I maybe have had on PC.
2. No quick reply in the push notifications. As other reviews have mentioned all other messaging apps have this.
3. Takes time to authenticate every time I open the app on wifi or 4G. Worse on 3G and essentially unusable on 2G.

Get back into dev mode guys or Slack is going to eat you!
