This app is soooo annoying. I have been trying to do the impossible sandwich for a week now. Every time I sign in when the window opens it says all shops are no longer available, but then the same locations repopulate each day. Last night, the location I wanted said coming soon. This morning, it looks like the in store is open and available even after the start time, so they must have opened the quota. Well now half the locations aren't there! And then you refresh and more locations populate, but I still can't get my location to load. I highly doubt someone took it. I bet tonight the location I want will show as coming soon again. I don't know who thought this system was a good idea...
