Duolingo Used iPhone's Dynamic Island for Ads, Violating Apple Design Guidelines

It's a miserable change.

> Android users highlight a better system. On that platform, developers must separate promotional, transactional, and service-related notifications into channels. You can silence the ads while keeping delivery alerts or account updates.

> Notifications were designed to inform. Instead, they’ve become another tool to sell. Unless platforms enforce stricter controls or let users fine-tune preferences, the problem will only grow.

Moreover, Apple needs guidelines to prevent Apple's own apps (Wallet, TV, Fitness, Books, Music...) from pushing intrusive ads via app notifications:

> Apple customers aren’t thrilled they’re getting an ad from the Apple Wallet app promoting the tech giant’s original film “F1 the Movie.”

The Dynamic Island isn't what I'd call a "notification." Apps use it to show you something that you're actively doing or tracking right now. Using it to show ads is like stealing a piece of your visible screen real estate to set up a tiny billboard that says "buy Duolingo!"

> I get ads in my notifications all the time.

FWIW, I don't get any ads in my notifications except for that one obnoxious F1 movie ad from Apple themselves.
