It's also in the Tips app, which prompts via notifications to learn about new features in iOS after an upgrade. You can ignore it, or you can let it walk you through the changes to your device.
yeah, but who has time? Tips will spend 5 mins walking you through how to change the preferred colour scheme for the Weather app, when what I want to do right now is answer the phone.
Then, 2 months later, I want to change the colour scheme in the Weather app. Can I remember how? Or even remember where I saw to do that? Or even find the right tip? Obviously not...
The grandparent asked if this was supposed to be discoverable and the answer is no, Apple does not expect you to discover it. If you want to learn about it, it’s in the Tips app (that they prompt you to use). Not wanting to use the Tips app seems like a personal issue.
If it is a personal issue, it's because it's a bad solution to the problem. It doesn't provide the information I need when I need it, and provides irrelevant information most of the time.
I'm the customer. If your customer has a personal issue with your product, that's your problem, not theirs.
