Unfortunately we had to temporally disable OneDrive. We needed to update Dropbox, which stopped working just over a week ago. Dropbox is the only backup platform that is available on all versions of Time Master (iOS, Android and Windows). When we went to compile it, MS had changed the OneDrive code. We were not able to update it right now due to time constraints. We are planning on updating it again, but do not have any ETA on when we will be able to do that (my programmer is away on business for the next few weeks).
As a work-around, you can use the OneDrive app in Windows to access the backups folder. OneDrive -> Apps -> Time Master Backups. If you create a Dropbox account, you can copy over that whole folder to the root of Dropbox (you can use a web browser or install a plug-in). Then sign into DB in Time Master.
We are sorry for any inconvenience that this may have cause you and hope you can wait for us to get another version out there in a bit.
