Way too often, when I arrive at McDonalds, then pull up the app so I can get one of the deals, the app says I need to log back into it by sending me a link to my email to confirm that I'm still me, before I can use the app again. So then I have to sit on the drive through, and go through all these gyrations with bunch of cars pulling up behind me and holding up the line for a long time due to this app. Very unprofessional for an app to do this.
