In all cases it should be a website, not a "download our app"
There are no adverts on netflix, and I have a lot of subscriptions, but its still less (pro-rata) than I paid for satelite tv with adverts in the 00s.
Increasingly often, it is "download our app". And they will try to force it by sabotaging their website. I did a pickup order from Walmart once. You're supposed to take a numbered parking place and check in, but if you try it from the website on a mobile, it'll redirect you to download the app. There's no getting around it. I don't recall if I tried desktop mode on the website, but the website is a pretty cluttered widescreen mess anyway. (Fortunately at the parking area there's a phone number for checking in posted.)
I run into similar sabotage issues with Facebook (yes I am just a year or so shy of being a boomer). You can no longer use messaging on mobile, it tells you to download the app. Desktop mode does work, though (for now; I'm sure someone will try to take it away). All this stuff used to work on phones.
One of the things I'm surprised they didn't mention is cooling. Cooling converts the starch in rice, potatoes, and pasta into resistant starch (and it stays resistant when you reheat it because nobody really likes eating cold potatoes). Starch normally gets processed by the small intestine into glucose but resistant starch is digested in the large intestine, so glucose levels don't spike. There are a number of other benefits described in the articles below:
