User blog:Oldguy22/Help to transfer accont

I have a few questions:

If I transfer me accont can I lose me things (or my acc) in that?

Do I lose gems when I transfer me acc to anoder device?

Can I transfer me ac that is on a tablet to an Ipad? Does it have some kind of bug?

Do I need to have the facebook app to put me old accont or is just put me facebook?

If I put a new acc if anoter facebook logged in can I put me old back or I need to uninstall the app and install again?

Please awnser all the questions it's very important to me.
