At the point in time when I disabled notifications for the app, it did not. I tried that. Even after navigating dark patterns, digging into the menus, and turning those options off, I still received promotion notifications.
Perhaps they've fixed it since? I don't know because they've already burned my trust and they've done nothing to earn it back. Publicly acknowledging and apologizing for this would have been a way to start getting off my list of bad actors.
Even if they've made it possible to successfully turn those off deep in the menus now, whatever dreamed-up definition of "opted in" it's operating under is a tortured legalistic one that undermines the actual meaning and spirit of opting in.
