You need a landing page to smooth the transition, and this offer really needs a lander period.
2) Your targeting SUCKS
2a) Stop mixing countries
2b) Make different campaigns for more age groups
2c) Remove some of the unneeded targeting (intent types, etc)
2d) Reconsider login count targeting and your bid pricing
3) Create a landing page! This does not have to be as difficult as people think it is. Find someone on fiverr if you need to make you an ugly lander with a big picture of a girl, a strapping headline, a few bullet points and a "Continue" button
4) Profit.. literally.
