fix the onedrive path/file name length restriction for God's Sake. You have known about it since Windows 7!
Seriously, no other cloud storage service provider has this problem. You have made your product useless to a large percentage of your users by restricting the path/file length which in turn causes OneDrive to crash during synchronization. FIX THE PROBLEM. You patch every other glitch on the planet, fix this one or continue to lose customers to Sugarsync and Dropbox.
