One of Additional field can't change when edit Request over mobile SCP app.

Good day Sir,

We have been made and used some additional fields at Request templets.
It works well over web browser on PC etc.

But when we edit Request over mobile app(both Android, iOS),
one of additional field(UDF_CHAR4) can't change.

Speaking exactly,
when the value selected one of picking list by add new Request on PC first,
then, it will be assigned to other Rep. who are on outside duty,
and if he or she try to edit that value of additional field using mobile SCP app.,
it didn't change to any other values of picking list, but only the value selected first.
Please help us.

And, One more thing need your support to make perfect mobile app for iOS,
There is no Request #No at any kind of Request list view.
(It shows well on Android device.)

Thanks.
Yours, KCSONG
