How to stop notification in posts? ..

Answer 1

For Q&A questions, tap the star icon below the upvote/downvote buttons to unfollow it.
I don't think you can stop notifications for lesson comments.
You can also go into your settings and disable push notifications for likes and/or comments for questions and comments (but I think you still get them when the app's open).
