I've been encountering a problem recently with the way some of my files sync to the "your work" cloud service. It's only been happening on the last few files I've uploaded, and essentially, the problem is that I'll upload an MP3 or MP4 and it shows up in the cloud as an MP2 or OCTET file, respectively. This has not to me happpened before. Does it have to do with the file size? I also can't preview it in the app or online, but will it convert back to the original file once shared and downloaded by someone else?
