Hey @TobiasBari, thanks for reaching out to the Dropbox Community and happy Friday!
We really appreciate your feedback about our desktop application. I will make sure your comments are passed along to our team.
As for the issue you're having, do you mean that the sync status of the application is stuck on 'Starting...', when you hover your mouse over the Dropbox icon in your system tray?
If so, is it possible that you have more than 300K files in your Dropbox folder at the moment?
If that's the case, can you use selective sync, to reduce the number of files, to see if that helps?
Keep me posted.
