This is such a frustrating product because of ONE thing!! I have been using the PC version for a few years and it works great. Now I own a Samsung TAB S7 and excitedly loaded Xodo to the tablet, Sadly Xodo's workflow is noting but appalling!! You Open the File & MUST save to Edit or make notes on the file. YOU CAN NOT SAVE THE FILE IN THE SOURCE FOLDER!!! It does not offer the folder It does not allow you to save in ONEDRIVE You have to Save the file in a local drive Make the notes, Save changes, Flatten if needed and then Share the file to into the Onedrive. Such a waste of space, and time Developers Please Please: Make the forced save an option I can turn off 1st offer the source location for saving an edited file
