Hi @Verdis, welcome to our community. You can only sync the two of them on king.com with a computer. Do you have access to a computer? You can follow the steps from here.
I have entered the link you gave me and I think I have done all the steps. Now the iphone tells me that there are connection problems and does not let me do anything (play yes but without connection)
I go in with the email account and see my 6k levels,
but I can't log in with Facebook because of the problem I told you about
connection, so I can't see if it's synchronized
Are you not able to log in with Facebook at all? The players who are writing about no connection are able to get into the game but then they get the message no Internet connection. Try clearing out your phone and follow the steps from here. Let's see if the troubleshooting helps.
@Verdis, unfortunately the only way to get rid of that message is to uninstall and reinstall the game but I have to warn you that you will lose all lives and boosters because they are only saved to your device. All gold bars will remain because they are saved on their server.
Hi @HisBeauty55, if you would like to sync both of them together you need to go to king.com and follow the steps here.
