1) The app refreshes the page every 3 seconds. Sometimes due to various delay, it may take 2 cycles of refresh to see the current stations, so generally if you wait for 5 to 6 seconds it should refresh automatically.
2) I am not sure about the cloud data warning and why you can’t edit stations. I will have to let Samer answer this question for you.
If would help if you can specify which Android version you are running, as some of these issues are directly tied to different versions of Android.
I am also curious if these issues happen in your phone’s browser. You can open a browser on your phone and type in the IP address of the controller to access it.
