Hi I'm sort of new to vaping and I recently bought an evic vt after owning a pen for a long time it worked great for a couple weeks then all of a sudden it started acting strange whenever I use wattage instead of temp control it tastes burnt and whenever I use temp control I can only rip it a couple times then I have to take the tank off and put it on again or else it goes into temp protection immediately and I barely get any vapor as the wattage then goes down significantly as well as the temperature anyone have a fix?
