It worked well for me last night and this mourning, getting about 0.5ETN/hr except that it did not transfer the pending balance to my account at 5ETN as stated in the info. Then when I got to 6.04 ETN , it just stopped increasing my ETN. It appears to be mining just no increase in balance (been like this for about 10hrs regardless of reloading app/rebooting phone). Still got some bugs I guess.
