What do you mean by notifications from where? Do you receive them via email? Or through a Telegram bot?
So far, I've been receiving notifications about karma just fine through the Telegram bot created by PX-Z, which is really helpful. Additionally, there are mentions, replies, or quotes to my posts that I can easily check. It's truly helpful, and up to now, even though I don't know which posts are getting karma, I don't mind that.
