Wayneo,
Yes I have updated to latest firmware. If it's a theme issue then it happens with the stock theme that's being sent out by Lost Vape and it's also happening on the theme that I downloaded from the forums. So it doesn't seem to be a theme only issue. I could change the '% change' but it doesn't seem to trigger according to that. It seems to only happen when I've taken the tank off and put it back on or when the mod has sat for a period of time and it has timed out. So say I take off my Reload RTA and then put on my Crown III tank. It will trigger the new coil message. If then hit yes it will it will go back to main screen and if I try to fire the mod again it will again trigger the new coil message. It will do that over and over again until I hit no and then manually change the Ohm's myself. Then of course the Ohms are not changing real time with the coil and only staying as what I input them as.
Edit: To add that it will also do it if I've left the mod say to sit and charge overnight or have left it sit for an hr or so and the mod has locked and timed out.
