Yesterday I bought a new Kanger T3S to use on my mvp2.0 and it worked great. I wanted to try a different flavor so I put a vision vivi nova on the mvp and used the t3s on a vision spinner. Today, however, I put the t3s back on the mvp and it won't work. The mvp keeps giving me the non message. What did I do wrong? Also, the vivi nova reached a place where I could get very little air flow and it's like sucking through a closed up straw. Solutions to my problems?
