I disabled it on my phone a few months ago. It was classic “out of site, out of mind”. I logged in a few weeks later and still the same useless crap in my news feed. I logged in saturday and, same thing. I’m over it.
I had much the same experience. Deleted the app from my phone, which meant I no longer received any notifications. Now I log in occasionally, usually it’s because I come across a post there that’s newsworthy for other reasons. When I do, I’m pretty unimpressed with what I’ve been missing.
