My lives have disappeared on one of my iPad

The page where it asked me if you could use my email disappeared. Yes, you can use my email. I will mention that one day last week I noticed my avatar changed with this have something to do with it? I didn't change it when I opened the app to play it changed and I'm thinking that's maybe what removed the lives I had whatever you need to do to get them put back on my iPad because that's what I use the most play with. I would appreciate it.
