I'm trying to figure out how to best reduce the daily earning notifications for infrequently engaging users. The biggest problem seems to be that this notification does not scale with engagement - it's daily, which might be more frequent than some users engage.

I can perhaps show the earning notification only once at the top of notifications upon checking notifications for the first time in a while; if it's been several days since you've checked your notifications, it'll accumulate the earnings since then.
