My sister & I share an Apple ID for applications (we have our own separate iCloud accounts) and whenever I try to add something to passbook, it shows up on BOTH our phones. It's like we're sharing one passbook. I can delete things from her passbook (from my phone), and she can delete things on mine (from her phone). If she has adds a gift card or a movie ticket, I could go use it from my device. Is there any way around this? It's absurd that it's making us share our passbook with each other. Any help would be much appreciated.
