Shares work, web interface slow/unresponsive

I am still so frustrated with my MyCloud 3TB.  The shares seem to work just fine, but I cannot get the web interface to work.  I just did the 40sec reset, and still I cannot access the UI.  WD Discovery finds it very quickly.

I’m using the latest firmware with no mods ever to the OS.  I just want it to work.

With the firmware v4, the UI is very slow. If you can’t live with it until a fix is delivered, you could consider downagrading to the v3 firmware.

Can I downgrade without the web UI?
