Cannot Access Purchases from Other Devices

[Simmias]

I purchased the Uber Pack on my iPhone. I tried to access it on my iPad, but it is locked. Both devices use the same iTunes and Game Center account. I tried the Restore Purchases option, but it didn't work. Do I really need to spend another $2.99 to get the Uber Pack on my iPad? Since most apps are universal, this caught me by surprise.
