Landscape PDF form fields display entered text 90 deg vertical on other devices

Hi,

I create the pdf with adobe acrobat XI Pro in landscape with multiple form fields, save it as (reader extended - more form fields) for email distribution.

It produces the pdf, displays perfectly, but on mobile devices any text 'entered' into the form field is vertical, i.e. 90 deg to the form field.

The odd thing is, any text in the form field before saving is saved correctly (see image. the '12'). But as soon as you touch the form field that text is instantly rotated itself, touch somewhere else it returns.

Is this some transposition error in saving because the form is landscape? I can't change the text property prior in the form fields anticipating the error or on pc they would be wrong. I can't find any solution or this wouldn't be my first post.

Any help would be appreciated.
