I just purchased an eleaf I stick 20 Watt. I used and it worked fine. When I was cleaning it I messed up the atomizer so I replaced it with a second atomizer that came with the Cloutank M4. When I put it in the second at8I still get a no atomizer. I also have an atomizer that us for a G pen. It is brand new and I am still getting no atomizer on my screen. I also made sure the I stick was fully charged and nothing has changed . I still get the message No atomizer. What can I do.
