One the reasons why it took so long (2 months to approval) is there isn't a clear set of rules for success.
When you submit to Play store or Apple store, there's a list of guidelines and checkbox reasons why you get rejected.
With Slack, it's more like having a conversation about making it better, not necessary a fixed set of rules.
It probably didn't help that we submitted in mid-December when most people were already on holiday.
