Hi there, recently bought a new smok stick v9, no issues with initial product and both coils worked fine, ordered replacement coils and when I start to vape it feels like nothings going in my mouth like there’s not drag/hit of anything, basically feels like I’m vaping just nothing until the vapour then leaves my mouth, I wicked the coil before and left it in the tank for 30 mins too on the 2nd attempt after again having the sane problem on the first attempt, using menthol grape liquid and can only taste the grape and not the menthol, any ideas please?
