It seems impossible to further edit on Fill & Sign Mobile App. an entry in a document that was entered using the Fill & Sign tool in Acrobat Reader on a PC. As an example, I used the Fill &Sign tool in Acrobat Reader on my PC to enter a set of initial data into my document. A day later, I would like to modify one of those data entries using the Fill & Sign Mobile App., but this seemed impossible. Such a feature will be very useful to those who need to further edit a document while being away from their PC's and carrying their smartphones with them..
