Drop box running smoothly for the last few months. This last week numerous issues. 1st the icon app in the tray stopped working. If I click on it I get the standard Windows 10 messages which basically says do you want this app to make changes on your hard drive"? I say yes and nothing. Still no app. The small icon that gives you the symbols when syncing/synced, etc. has no symbol just the icon in white. When I right click it's empty except the message "could not load content". .
