Why don't my friends appear across the bottom of my ipad?

My friends do not appear across the bottom of my ipad. Only one friend appears who is ahead of me! How do I fix this?

Hi @Penster, have you been seeing them all along and now you don't?  Are you playing through Facebook because there is a Facebook glitch that has already been reported to them regarding the lives.

Yes, I used to see all of them now I only see 1. I am playing linked to fb

Well there is a Facebook glitch that they are trying to fix so it might be affecting your game.  We have to wait for them to fix it.
