Yea I found android better at preventing ads, when I switched to an iPhone I noted that policy and was relieved that I wouldn't be bothered with ads again; only to find that most apps for retail stores still send me coupons and deals with zero way to turn them off, android has granular notification settings so I could turn "promotions" off but keep "order notifications" on, meanwhile that isn't there on ios and most apps don't have settings for that inside them either.

I will also note that whenever an app would't provide the option to turn off promotions on my android i'd just make buzzkill filter to only allow notifications with the word "order" meanwhile any functionality like that wouldn't be possible on ios, i cant even change the notification noise for most apps!
