mate you are missing the point, if you have a photo editing app and you ask for consent to edit a photo, that's not consent to also use the photo to do something else with it

> I mean, this is kind of nuts. Should they ask consent every time you click to navigate to a new page, just in case you didn't want to see it? What level of granularity is acceptable?

I think your comment is obtuse and that you did not actually try to understand what the GDPR is saying but anyway: no, it doesn't concern itself about that dimension at all. There would on the other hand need to be new informed consent from the user before their data can be shared with new parties or used/transmitted/processed/stored for new purposes or extended time/space scopes.
