answer:Because the functions available in the app are controlled by the developer of the app. The Internet, of necessity, must be available to as many browsers as possible or the site is limiting their traffic. The same thing used to happen with the old Flutter app. It had limitations built in so using the mobile site was always preferable. I don’t us any app for which there is a website available because, to me, it just wastes space on my phone or tablet which could be better used for apps which can’t be accessed by a browser. The limitations imposed by the apps are usually too annoying to deal with for me. I’d rather used the website. So it takes a few seconds longer for pages to load? Not a big enough problem for me to justify using an app which cripples functionality. I’m not in that big a rush.
