I have successfully published a couple of apps with the ZapWorks Studio. Both of the apps use the Z.getJSON method to fetch live info from web services hosted externally. The apps are working great in the Windows emulator and on my iPhone 7, but when I try on Android (Galaxy S5 neo and ancient old Tesco Huddle tablet) the JSON feeds are not loading and I get a message where the info should be saying, ‘Check your connection’. Both Android devices can surf the net fine and have strong wifi signals (am based in a University). I have another app which just fetches a web page when zapped and this is working fine across all platforms.
I’m not sure where to start with the troubleshooting, can anybody help, please?
UPDATE: I can see the request being made from the Android Zappar app to the external JSON feed (Zappar is using AWS). The first request to access the root directory ‘/’ is working but it’s not making the second call to the JSON feed, whereas on iOS both the request for the root and the JSON feed are being made.
