Massive improvements to sync required
Two devices, sync seems to fail often, create conflicts regularly and simply not be fit for purpose. Any more than about 100 files hosted and the service is pretty much unusable.
I just lost data thanks to this issue.
I was working on a word document throughout the morning, with autosave on as it was in a sharepoint/onedrive folder. I closed the file, switched over to another PC, opened the file and the changes were not present.
Opening the file on the original laptop now shows none of the changes and there is no version containing the changes in the version history to be restored.
