Notifications for new comments on followed posts



That already happens for content you follow on the website. By default anything you reply to is followed, unless you disable the option or manually unfollow.
If you're on the app that doesn't exist though I think you may still automatically follow content your reply to.


There is an email option for content you follow that can be enabled on the website. If that is turned on and you're not getting email, then it's possible the app doesn't auto-follow .
