So i was sitting here and watching youtube and vaping some Virginia Fire Cured tobacco in my mini protank, and suddenly my itaste just stopped working. As in no light on the fire button, the led screen didnt come on, nothing. i tried the 5 clicks to turn it on, i tried messing with the up and down buttons, i plugged the charger in took it out, and nothing. Then about 5 minutes later it starts working. Does anyone have an idea as to what the issue might be, as well as how i can prevent it from happening again.
