Hi - my dropbox icon keeps dissapearing from the taskbar of my MacBook Pro (Retina, 13-inch, Early 2015). I am running High Sierra 10.13.6 and my dropbox is version 228.4.5567. When the icon dissappears files stop syncing. I can also no longer open dropbox from an icon placed in the toolbar but have to double click the icon in the applications folder. (dont know if this is linked). When I do, the icon reappears in my taskbar (the one at the top of the screen) and syncing restarts. A day or so later it will then dissappear again
