Force Synchronization after upgrade?

[eg-yale]

Hello - I've been trying to upload a large number of video files to S3 using Mountain Duck in the background (totaling over 1tb). However, even though the files were there on my computer in the mounted directories when I checked in Cyberduck it looked like, even after a few weeks of running in the background, there had been very little progress at actually uploading the files. I had been using Mountain Duck 4, so I decided to upgrade to Mountain Duck 5 since it said that this would allow auto-resumption of large files and a sync manager so I can better see the progress. I set it to use Integrated mode. But now that I've done so, Mountain Duck isn't reporting any activity at all. I'm guessing this is because the files were already there in the mounted directories on my computer - is there a way to force synchronization and see what files have been uploaded?
