One thing that has been slowly creeping in is a little bit of a Microsoft-like "you will use our feature", like launching apple music every time I hit headphone controls, or nagging me to turn on reactions every time I start a video call. In some ways that's more annoying than the outright bugs, as they could choose not to be that way and market themselves as not being that way.
I feel your pain. I hate pushy upsells and promos. Also the cluttered settings App "Remember to setup Apple Pay" promos. I do value user education. They need to consolidate all of the feature promo services into a revised Tips tool that allow users to engage with new features at their own pace.
