I too haven't been able to get suggested apps to work. I've toggled the switches in settings on and off and even rebooted my phone to no avail. Only time I have ever seen it work was on beta two for me. Very strange.
Noticed this for the first time yesterday when I was outside one of the banks I'm a customer of. Was surprised they had it set up to be honest, unless it's not something set up by the app developer?
