I did get the Immigration App working via Mobile Data not on home Wi-Fi. I have seen this type of issue before with other Apps. It has something to do with IPv6 network connectivity.
The Android app has stopped working for me for several months now. It doesn't connect and times out right from the start. I have used the WEB site for my last two 90 day reports. Before that I was able to use the Android app. Has anyone else been successful in using the 90 day Android app recently?
