Hello. I have created a document with fillable fields using Acrobat DC, and have applied a permissions password to this document. It seems that since applying a password, the document fields no longer function in iOS. My guess is that the document was flattened when opened in the mobile applicaiton. I have conducted a test with the same document, unlocked, and the fields remain active.
Also, is there a way to turn off the purple highlight covering the fillable fields in iOS ? The colour overwhelms the design of the document and it would be nice if it was offered as an optional feature.
It sounds like you are not using Acrobat Reader Mobile (beta). Please confirm and I can move your post to the non-beta Acrobat Reader Mobile forum.
The beta forum is rarely answered and most posts that arrive here belong in other places.
