I bought a smok stick v8 yesterday and it worked amazingly well until this morning. the button flashed a bunch of times and it turned itself off and will not turn back on. I put it on the charger and the button flashed four times. I have cleaned the threads between the battery and the tank, replaced the coil, refilled the juice, and still nothing has worked. any advice is greatly appreciated and know that i am very new to vaping so I will probably asked some dumb questions. thanks!
