I had to completely turn off notifications for Instagram because none of the provided settings appear to disable the almost-daily "for you" and "trending" notifications. Now I don't get notified when someone DMs me there, which has lead to me missing important messages.
Same. And I used to work there, and I raised it with them. They have all their career incentives aligned to getting people to see spammy notifications. I was powerless.
The problem with the user hostility is that, in the long term, people don't use it.
As a web dev I see so many things that are lights-on-nobody-home about Meta. The Meta app on my phone generates numerous notifications, when I get one that says a game that looks really cool is 50% off, clicking on it doesn't send me to the landing page in the their app store, it sends me to the senseless home page of the app which seems to have the message "move on folks, nothing to see here"
The Instagram web application fails to load the first time I load it on my computer and I have to always reload. On either Facebook or Instagram I am always getting harassed by OnlyFans models that want me to engage with them... on the same platform where I engage with my sister-in-law.
When they say they are "careless people" I wonder if they are not just careless about sexual harassment and genocide but careless about making money because we're in a postcapitalist hell where Zuck could care less for making money for his shareholders but rather gets a squee from sitting behind Trump at his inauguration and hires people with $100M packages not because he wants them to work with him but because he doesn't want them to work with someone else.
I went through a couple rounds of trying to raise specifically this issue with support before simply uninstalling the app out of principle. They had their chance and burned it.
1. your profile icon (bottom right) > hamburger menu (top right) > Notifications > Posts, stories, and comments > turn off ‘Posts suggested for you’ and ‘Notes’
2. on the same screen, set ‘First posts and stories’ to ‘From people I follow’
3. back out to Notifications > Live and reels > turn off ‘Recently uploaded reels’ and ‘Reels suggested for you’
This works for me, but if you’re still getting notifications you don’t want, you’ll have to figure out what category/type they fall under and turn that off.
