Facebook notifications.

Is anyone else having issues with Facebook hiding notifications that are actually relevant?

I made a post a few days ago and didn't get notified of the comments I'd received. Today, I apparently got an invitation to a Facebook group and was unaware of it until I received a DM from the moderator asking me to answer a few questions before I could join.

I don't think I've had the issue recently, but Instagram sometimes will notify me of things a day or two after the fact and I know Instagram and Facebook are put out by the same company.
There's a place to find your notification settings. Click your icon in the right hand corner of the screen, hit settings and privacy, settings, and then notifications. Maybe something got turned off by accident.

Closed upon OP’s request.
