Your backup helped me identify several problems in the code that uploads files to OneDrive. The nature of the problem is that the upload will finish, and then MobileSheets tries to obtain a reference to the item in OneDrive to ensure that the file was actually successfully uploaded (as I've seen cases where the Google Drive and OneDrive libraries would say an upload is completed but then no file would actually show up), but the code to obtain the item was failing. I'm not sure if it was failing because I was querying too quickly after the upload finished or if it didn't like something about the query itself. I modified the code to obtain the item in a different way and it's all working without any issues now. I'll roll out the fix as part of 3.8.7.

Thanks,
Mike
