I have mycloud ex2 ultra device and trying to sync back & forth from users pc files using wd sync.
When I tried to connect to mycloud from wd sync it says remote connection fail. & its not connecting to my wd mycloud device.

Does wd sync is still a valid software and we can use with mycloud device?

How to sycn pc files to mycloud device?

Thanks

WD Sync is not supported on OS5 and further is end of support. WD apparently recomends one use Goodsync as a replacement. Or one can use third party sync programs.
