Why can't I login to my google+ account in Minion rush?

I have 2 devices. On one device I can see 2 buttons to register/login as facebook or google play games. On the other device I can't see these buttons. All the rest is there, only the register buttons are missing.

Solution 1:

Most likely it's because you don't have updated either Google Play Services or the game itself. You can update Services through Google Play.

Solution 2:

I just had this problem on a device that used to be mine, that I was setting up with a different profile for my daughter. It wouldn't give me connection options. I uninstalled and put her in as an 18 year old, and then it gave the social media options.

TL;DR: maybe it's set to too young an age
