That and the horrific dark pattern on the "We want you to have the best, massive red/orange button marked continue that takes you to the app store and the tiny weeny little "continue to mobile site" underneath".
I don't want your damn app, stop asking me.
If I was cynical I'd think they didn't care about the mobile site been awful as it drives people to the app.
