Hi there, please help me. I was using Vaptio Cosmo 2 for a while. However, after moving to the US, I broke my Vaptio mod: but Vaptio doesn't do their business in the US anymore. I saw an article from ECF, and people were saying you can use a tank on a different band's mod under that article, so I bought a Vapresso gen fit 40 mod (both the mod and the Vaptio tank are 510 thread). Unfortunately, when I connected the two, Vapresso mod couldn't trigger the Vaptio tank. Do you have any thoughts about this issue? Thanks!
