Chinesepod option not appearing on bottom of ipad

I have 3 devices that are synced to my skritter acount. Two of them loaded the chinesepod option on the bottom of the list page but the third one did not. How do I force it to sync and install the chinesepod option? Thanks

If it’s not popping up, I recommend clearing the local data: http://docs.skritter.com/article/13-local-data
