Q: How to

I have spent lots of time rearranging the order of my books collection on my iPad's iBooks app.

For example - my preference is

- grouping books in a series

- which books I want to see first

- grouping books from same cover designs and publishers

- basically its visually easier to see and quicker to navigate to the appropriate books

Without notice after I sync my iPad with new books, the order in each of my collections gets jumbled up again!

ARHHHH!!

I have given up on reordering them again until I find a fix as it has been reoccurring on all my collections about the fifth time this month.

Can anyone help? How I can stop this from happening?

On my iBooks on my Mac, I have them in the same order of preference I wish to see it.

I just wish Apple would have considered to keep the order as my Mac so I don't need to rearrange again on my iDevices, however I can bear with this if it actually stick with the order after I custom reorder the books on my iPad.

Macbook Pro - El Capitan 10.11.4

Ipad Mini - Latest iOS 9.3.1

Would love to know if others are having the same problems and what they have tried as a fix.

Any help or suggestions much appreciated.

Thank you so much in advance.
