Known limitations and managing user expectations:

• Only Team owners will be able to create a new activity
• Each team can have a maximum of 30 private channels and each private channel can have a maximum of 250 members. The 30 private channel limit is in addition to the 200 standard channel limit per team
• Deleted channels will account for maximum channel limit in a team until the retention period of 30 days
• The bot will not be able to determine if a channel with same name exists or if the maximum channel limit is exhausted in a team at the time of creating an activity. A summarized status will be shown to the activity authors after the activity is created
• The app will create the randomized groups of team members even if it is not able to create channels on the user's behalf
• It is outside the scope of the bot to determine if a particular activity is completed or not
• Bots and Apps cannot be added to Private channels. In case Private channels are requested to be created, the app will not be able to @mention users or send due date reminder notifications in those channels.
