I cannot understand what is messing up this synchronization. Also I don’t understand why the number of out-of-sync items on the 2 sides are not matching?
I have waited for a long time and the number of files out of sync is not changing on either side.
Any help would be very greatly appreciated.
Thanks
As @tomasz86 wrote, upgrading is a good first step. Then if they persist, have a look at the locally changed items. They may be preventing further sync.
