I have been opening pdf file Forms in Acrobat, changing them by filling in the feilds and then saving a copy into my Onrdrive account for the last couple weeks no problem. Now when I try, the option for One Drive isn't there! Why? How do I fix this? Help! I've been searching the web for bug fixes for hours and don't know what to do. I have completely uninstalled and reinstalled both Onedrive and Acrobat Reader and the same problem exists. Soooooo frustrated. I can't still do it on my phone but not my tablet. It makes no sense. I need this for work. Ugh!
