Mobile Device Cycle Count Error (CU9)

Hello!

We recently upgraded to 2012-R3-CU9, and now get an error on the mobile device when doing cycle counting:

• Creating cycle count work through a cycle count plan (works fine)
• Enter a "starting location" on the mobile device, and the system loads the screen with Product Info for the item to be counted.
• Inventory Status is preset to "Available" by the mobile device.
• As soon as I enter a quantity, I get the error "The Status is Not Valid".  It also clears the Status field (but doesn't allow it to be changed)

For setup, I am using "Use Work" and "Cycle Count grouping".  We have exactly the same setup as our CU8 environment had, and everything worked well there...

Is there something specific to CU9 I need to consider?

Thanks in advance!
