I read news sites I pay for by scrolling through the home page and opening stories I want to read in new tabs, and then slowly reading and closing them throughout the day. Your app can't do that. Your app doesn't support tabs. It also doesn't support basic things like letting me zoom in on an image. And sometimes it crashes when I try to load comments.
I'm a paid subscriber, and I still get constant nagging every single day to use the app instead that is worse in every way.
And I don't even know why. They're just news sites. They don't ask for any permissions to slurp up my data. I honestly don't have the slightest idea why they keep pushing the app.
