We have a production merchant who informed us that they cannot exit the below screen when this screen comes up on the Station 2018. (It doesn't seem to be happening for other device models like Minis)
There's no way to exit this, and they have to restart the device. And during a very small 5 second gap where the device is starting up, and just right before this app starts again. There's a way to open up another app. If not, this Ordering.app screen takes up the full screen again and they have to do the device restart all over again.
Any idea why this is happening, or how to prevent this?
