Granular notification controls are currently limited inside of Debut. You can turn off General Notices by going to More > Settings.

If you would find more granular controls helpful in a future version of Debut, let us know by sending an email or sharing how you'd like to see this implemented on our Backstage Community Channel.
​
iOS and Android offer robust settings for managing notifications at a high level, so if you're getting too many notifications, you can have these delivered quietly in summary form instead.
