After what I think is the latest update there now seems to be a problem syncing files with Swedish characters across all sources like Dropbox, Google Drive etc.
You can see the menu icon working constantly and eventually you will have a bunch of files on wait/retry. If you click on a file to sync it you get an error saying it does not exist.
I have tried unsyncing everything and removing the storage connection without any success. This issue also seems to only exist when trying to sync existing files, syncing new files I put in the folders on my computer works fine.
