I was able to upload 2.4k tracks to my dropbox successfully, however there are 22 tracks which are just not uploading for some reason.

They continue to try to upload each time I launch Mixo as well, and still return the same error - "Cloud Storage is Full". I first saw the error when uploading about 2k tracks, and when I clicked OK it just skipped the tracks and continued uploading the remainder.

These are all .flac files and spread across different folders on my laptop. I am able to play the songs in other apps as well as Mixo.

Just a bit curious as to why this is showing up. My dropbox account has 2TB storage and space is not the issue :)
