Hey guys , recently got myself a Smok X-Cube 2 and I seem to be having an issue with the temp control. This is the first time I've used temp control (with Ni200) and found out that I need to set the temperature coeffecient. Now HERE comes the problem. When I enter the app , the entire section for temp control is greyed out. I cannot even select Temp Control mode in the app , and I'm becoming frustrated. Must i purchase the SS and Ti upgrade just so I can use the Ni200 (which i thought came factory)? Or is this an issue others have experienced/fixed? Any help would be greatly appreciated! Unfortunately my Google-Fu was not able to help me
