Praveen says he will "mute the group if I anticipate a lot of non-critical notifications." I think the anticipation of a busy chat group is a safe assumption. Muting for an hour or a day would be a welcome feature. Or show only messages that at-mention you for a period of time.
Are you using Kaizala group chat? What is your experience when the chat is being posted thick and fast? Do you have any tips for managing notifications or does it rely on group members forming their own best-use guidance?
