Over the past two weeks I have been receiving reports from iPhone users on AT&Ts network that sales are not loading on their map. I have begun investigating this problem and it appears that AT&T is blocking the communication path for some reason. While I run this to ground, if you are experiencing this problem please comment below so that I can keep track of who is affected.

This morning I submitted an update to Apple which I hope will fix this problem. I don’t know for certain, however, since the problem is so isolated that I can’t test correctly. It appears that SOME AT&T networks are modifying the sales response from the server WITHOUT showing any sort of network error. Also this seems to only happen in places that are very busy with yard sales. Basically, iOS + AT&T + busy yard sale area = risk of your app not working.
My thinking is that the sudden spike in server traffic is flagging something in a firewall somewhere. I have also pushed the issue up to Apple to investigate. Once you receive the new app update please let me know the status of the issue.

09/11/14 – With the latest app update this issue appears to be resolved. Please let me know if you are still having issues!
