I need some help. I recently bought the ijoy capo 100 mod a couple months ago. When I first got it, I was having the same issue I'm having now. The tank would fully screw into the mod no problem but then after a couple weeks, it would stop just about to the end. A gap is barely visible between the tank and mod when this happens, and the tank will wobble in top. The mod will still fire, but the voltage is significantly less than what it used to get under the same settings. I've tried other tanks with the same mod and get the same results. The first time I had this issue, it was a couple days after I bought it, so I went to the same vape shop and they swapped it out for me. Not sure what to do now since it has been a couple of months since the exchange.
