I wouldn't mind the constant redirects to the app IF the app was actually at least as functional as the website. The problem is that the app is less functional, which is infuriating.

1. image quality on the app is substantially worse than on desktop; a problem when you're trying to zoom into a large menu with small text

2. you can't search through image captions (i.e. to see only pictures of a particular menu item); possible on desktop but not on mobile
