Hello, before iOS 12, we were able to see each others books as we were on a family sharing account. Now, there is no "purchased" tab or link in the Books app. It is not under iTunes either. We have books sharing and family sharing on. We signed in and out. Going to my partner's iPhone and looking up the same book prompts him to spend another $20 for the same book. He cannot even look up one of the books I purchased (won't show up in search). Any one having the same problems or any insights?
