I noticed that the App does not enable calculations because when I went to calculate mileage reimbursement for my work it says: "This document contains some form fields that are not supported in the viewer. Please use Adobe Acrobat Reader to fill the form." Then it adds the button "Learn More" which takes me to the download of Adobe itself to install on my computer which I am trying to avoid doing because it slows down my computer utterly to a stop and because I like to have the App on my IPad so I can conveniently take my work anywhere I want. Could you possibly enable this function? It would be much appreciated! Thank you so much!
