Just to let you know that there is a bug with the free version :
One rule is to deploy at least one app within 6 hours.
If you do not then your server expire.
The issue is when you "undeploy" your deployed apps after the 6 first hours, then your server is removed with the same message "Your Cameyo Play server has expired".
Example :
10am -> create new free server
11am ->deploy first app
5Pm -> connect to server = everything is good
6pm (or after) -> undeploy your app = your kicked from session and your server is remove.
A free server that has no published apps will be deleted after 6 hours. That includes initially and throughout its lifetime. Likewise, a free server that has not been used in 7 days will be deleted.
Yes I know that. But from a user point of view this is a big bug. In fact when unpublishing the only published app, there should be a warning telling the user that the server will be instantly erased !
