Found a little problem for me, MobileMiner uses OS windows system name to show my rigs.
If i change it, MobileMiner begin to show me both systems, old and new, and old one is always offline. How to remove from list?
Are you using the Android app or the iOS app? In the iOS app if you swipe the row you can delete individual machines.
This feature isn't in the Android app yet but will be in the next update. If you'd like to let me know the machine name I can remove it manually.
