so, im new to vaping. I got a joyetech AIO a month ago and have been having some problems with it. It seems like every other time I replace the coil, I have issues. I prime the coil by putting five drops of e-juice in it and let it sit for a few minutes. Upon using the new coil, it's hard to draw from the vape, and the taste is really muted. Does anyone know why this could be happening?
