Share link icon - right click menu - disappeared

Is anyone else experiencing the below? Any ideas for a ‘fix’?

I have 2 identical P.C.'s I access a 4TB MyCloud Home device from one, and an 8TB device from the other.

Last night (25 Oct 2019), right clicked on a file on the 8TB unit to create a SHARE LINK, and the Icon for it was no longer displayed in the Context Menu.

I rebooted the P.C., reconnected to the Internet, and MyCloud, same thing. No Icon.

I rolled back to a previous backup this morning, where I knew the Icon had been present. Still not visible anymore.

The I looked at the other P.C. connected to the 4TB MyCloud Home. On that computer the SHARE LINK icon had also disappeared. It was visible and working 2 days ago

I had not made no changes to either P.C. No new software, updates etc.

This happened once before on one MyCloud Home device. I opened a ticket with WD. After 3 days, the Icon just came back, before WD replied, so I cancelled it.

It is highly unlikely that this is an issue that happened to both P.C.'s on the same day, unless it was an ‘in the background’ software update from WD.

Help!!!
