Good afternoon, I have a problem with my dropbox, a few days ago everything was still ok, I had some folders on the computer in sync with the drop and I could see these folders on the iPad and another computer and now this sync has disappeared and I can't indicate it in any way dropbox so that it syncs from my PC to the DB...I'm desperate as I need access to these folders outside the house and I can't resolve it...I haven't modified anything in my DB App for this to happen and it's affecting the my work...does anyone have my problem and any solution? when i click the files the option to sync to DB no longer appears, the app is updated...thanks
