Situation currently STABLE
(1) Removed SmartWare software from my computer (might re-install at a later date)
(2) Shutdown WD My Cloud, unplugged both My Cloud & My Book for an hour
(3) Plugged everything in and waited
Dashboard itself takes about 10 - 12 seconds to fully load, everything displayed considerably faster, all scanning stopped, all pages of Dashboard load quickly, any changes to settings take effect quickly. So at this stage almost as good as pre FW 4.00 upgrade.
Still have issues regarding Notifications showing incorrect time stamp (3 hours in the future)
Cloud Access shows relay connection it was a direct connection before the upgrade. Have turned Cloud Access OFF for time being.
AS I indicated situation stable won’t say it is resolved becaues the FW 4.00 resolved no issues for me and in fact created two that I know of.
Obviously have turned automatic firmware updates OFF.
