I could not find any information specifically about underground apps, so here it is.
1- What is the current process to transfer an underground app from an account to another?
2- How is it affected by the paid app available in google play?
3- In the case of buying an app or creating a new company account, let's call the new account target account. Would it work to transfer the paid app in google play to target account there and then also transfer in amazon the app to the new target account ?
4- The goal is to not loose the currently existing daily users.
