I have at least two apps on my iPad that seem to get never transferred to my iTunes library. One is "Insight Timer", a free timer app, and the other is "Audrey Grant’s Better Bridge", a Bridge learning app for $34.99. Simple syncing does not help, going to File - Devices - Transfer Purchases from iPad and then syncing does also not help. Can somebody explain this? Can this be fixed? Am I doing something wrong? Is this a bug?
