Hi, i use xodo to read and change pdf files and, up to a week ago, as soon as i closed the xodo, a notification appeared on my tablet informing me that there was an update to be made and, when i clicked, the dropbox started to update the changes in the pdf (I open the pdf in the xodo directly from the dropbox). Now it doesn't appear anymore. And none of the apps have any commands in that of this. I even found an option in the xodo of sending the file to the drobbox, and letting this new file saved there. but what I want is the files to be in sync and not that every time I modified them I had to send a new version to the dropbox. What happened? does anyone know how to make the dropbox start syncing immediately after i close the xodo app like it used to do?
