I was looking for books with "discipleship" in the title.
- On my desktop Logos 7, there are 9.
- On my iPad mini 4 Verbum app, there are only 7. Why?
- On my iPad mini 4 (same device) Logos app, there are all 9.
Moreover, when I looked at one of the two missing books (Real-life Discipleship: Building Churches that Make Disciples, by Jim Putnam) on the desktop, it shows the following (attached screen shot).

Why are some books only available in some of the apps? I thought the apps are interchangeable when it comes to resource compatibility? And they seem to vary from device to device...?
[Note: In case you're wondering, I don't actually own all these devices now. Only the iPad mini 4 and iPhone SE are current. I just have to go in and clean up the devices list.]
