It also consistently insists, breaks functionality and nags you to try and get you to use the app instead of the browser. Its barely useable from a mobile browser.
They can steal a lot more data from you using the app, that's why they insist on you installing it.
I avoid native mobile apps for anything but the most essential for this reason. If it wasn't for the cars and public transportation I'd be using a feature phone by now.
I don't really understand why people use an "app" anyway, when browsers exist.
